need help stat!

[alero_bmxer]

okay here's the problem; for my PRND321 light i replaced it with an LED strip. last night it came unhooked no big deal. tonight i took everything apart and saw that one of the connectors had broke, okay ill replace it. i replaced it and now my gauge lights and hvac lights will not work. checked all fuses (at least ones i thought were related) and un hooked all my floor and cubby lights that were tapped into the cigarette lighter. it cant be the dimmer switch because it will still turn the overhead lights on and off. funny thing is if i un hook the gauge cluster and hook it back up my blue LED's will flash for a sec and then nothing. need any help please i drive in the morning when its still dark out and i wont be able to see anything.

INTLPS fuse. Open the passanger fuse panel, its on the top right.


If not, there is one in the engine bay too... forgot the name though.

[alero_bmxer]

checked both of those and they are both fine. replaced with brand new in fact
. if you can find the one under the hood i would much appreciate it. i looked but didnt see any related to gauges.

[cherrington17]

there is one that relates to interior components. I had the same issue a few times... maybe #46? i don't know why that rings a bell...

[alero_bmxer]

#36 is AUX PWR/CIGAR but i checked that and it was fine

[cherrington17]

sometimes its #45 under the hood. Parking lamps.


Since its a major problem, instead of looking for logical names... i'd just pull them all(the minis) and check them visually or with a meter. (continuity check)

[alero_bmxer]

hmm ill check that and all other mini fuses.

[cherrington17]

if its not those, then its a short somewhere....


..but those normally blow fuses.


also... make sure your parking brake isn't pulled up at all. That will also cause that.

[alero_bmxer]

checked every mini fuse in the car and under the hood. parking brake is down and all after market lights are unhooked. still nothing :cry:

[cherrington17]

sounds stupid... but try tightening the bolts on each side of the dash, fuse panels.

(theres a center bolt that holds it together)

[cherrington17]

do you have a multimeter?

[alero_bmxer]

nothing. im starting to get pissed...

[cherrington17]

so... not start eliminating. disconnect the center led strip and see if it powers up.

if not, go to another interior light spot and disconnect....see if it works...etc

[alero_bmxer]

center strip, footwell strips, and the cubby in front of the shifter is also un hooked.

[cherrington17]

thinking..... thinking.....

[cherrington17]

until you get it pinned down, you CAN rig it so you have gauge lights, by running a power wire from the fuse box (any constant on) or from the cig lighter, to the gray power wire on the gauge cluster harness.

that should work to power the cluster lights so you can drive

[alero_bmxer]

ill try that. i mean could it be the dimmer switch at all?

[cherrington17]

yes, it could be...

[Lucalare]

Check the wires running from the dimmer switch to the lights that aren't working, they could have been unplugged/shorted

[alero_bmxer]

well ill rig the lights tonight and get a dimmer switch as soon as i can. so your saying if i run a wire from the cig lighter to the grey wire on the cluster harness it should work?

[Lucalare]

it should, but I think they'll stay on all the time, because the lighter works with the car off, unless maybe there's a timer on it like with the headlights and dome light.

[cherrington17]

oh... luca is right. it will be on all the time. So... connect it, get the lights on and working... then disconnect till you need it. :lol:

its ghetto...but it'll work.



BUT... there is a chance it won't work. If the gray wire is shorted (why its not working) then the lights might stay out... I really hope not.

[alero_bmxer]

F it ill just wait and see if its the dimmer switch i dont wanna screw anything else up

[Lucalare]

Call me stupid, but have you tried moving the light switch to the "on" position instead of auto. Maybe the automatic function just dumped on you.

[cherrington17]

if you have a multimeter, put it on continuity, and test your bulb wires (any spot that isn't working)

it should be "closed" and you hear a chime.

then disconnect your dimmer. if those wires are now "open" you found your problem. if they stay "closed" then its not the problem.

[alero_bmxer]

yupp tried everything i could think of. now that im thinkin about it maybe the power wire for the PRND321 harness grounded out on the metal part of the shifter and shorted the dimmer switch?

[Lucalare]

eh, in that case I don't think the dome light would work, but it's worth checking.

[cherrington17]

certainly possible. highly likely... best to test first...


the rheostat/potentiometer that controls the voltage might have gotten friend, but the switch is still intact... which is why the dome light would work.... its possible.

[alero_bmxer]

well when i bought the car the dimmer switch didnt work so the dash lights and hvac lights didnt work but if i remember correctly the dome light still worked.

[cherrington17]

well.... i hope thats the problem.

...can I go to bed now? :lol:

[alero_bmxer]

haha yes you may. i gave up im also goin to bed thanks for the help tho

[slownlow43]

The connector you replaced, was it the power or ground connector? Do you have power at the bulbs for your HVAC lights? The first thought that popped into my head reading the OP was a ground issue. Perhaps you don't have a good connection at the new connector or you shorted out the ground wire for those lights.

[alero_bmxer]

im gonna tear into it again tonight and keep trouble shooting. one of the techs at work looked at it and said the dimer switch is doing its job so i guess thats out of the question. cherry where is this regulator at so i can test it?

[alero_bmxer]

all fixed....kinda. ended up testing the interior lamp fuse and it wasnt getting power but the dimmer switch was so i ran a jumper wire from the grey illumination wire on the cluster harness to the switched power wire on the dimmer switch and bam everything works again (minus the dimming feature but im not at all worried about that).

[cherrington17]

so you aren't getting power to the intlmp fuse??

[alero_bmxer]

so you aren't getting power to the intlmp fuse??

nope i think it could be BCM related? could be very wrong tho

[cherrington17]

hmmm...... i'm gonna have to look at a haynes manual. or maybe PM lonnie. hes good at knowing where to find these things. :lol:

[alero_bmxer]

please do i hate having rigged things in my car :lol:

Here you go Cherry...this is the drawing for a 2000 2.4L. Power for the INST LPS is coming from the AUTO PARK LAMP RELAY under the hood on a brown wire to the RIGHT I/P FUSE BLOCK and is fused with the INST LPS FUSE at 10a. The AUTO PARK LAMP RELAY is fused with the PARK LPS FUSE 15a under the hood. Hope this helps!

There is a BRN wire running from the AUTO PARK LAMP RELAY to the INST LPS FUSE...this what you should test next. IF no power is present then you may have a problem with the AUTO PARK LAMP RELAY. You can also test the PARK LPS FUSE 15a if it is know good and getting power across it then the problem may lie with the RELAY or the BCM...should be a WHT wire from the BCM to the RELAY per the drawing.

[alero_bmxer]

wow thanks for the diagrm. ill check into it more tonight and let you guys know what i find.

[alero_bmxer]

finally had some time this morning to get into this a bit more. lonnie's diagram says that the instrument lamps are in correlation with the auto park lamp relay. well that relay has not been there for a long time (i removed about a year ago) so i don't know why that would just now be coming back to haunt me. im going to my shop in a little bit and once i have better testing tools ill poke around a bit more.

Wait a second...I think I have the wrong drawing...what is the make and model of your car and do you need instrument cluster lamps or interior lamps?...What lamps aren't coming on as of today...? In the instrument cluster drawing which I'll post in a second I see two fuses both 10a running from the LEFT I/P JUNCTION BLOCK..give me a second and I'll post the drawing.

[lonnie]

Here is the drawing..had to crop it. If you want better versions I can email as a .pdf. Or you can go to this thread: http://www.aleromod.com/forums/showpost.php?p=305708&postcount=1

Use the above to find the drawings you need. Should help you with troubleshooting...If you have wiring other then stock then you will need to account for what you have wired up. Anything that myself or anyone else helps you with is with the assumption that we are working with stock wiring.

[cherrington17]

Why would you remove the auto park relay?

..and if you did a while ago...that should have killed the interior lights immediately... :huh:

[alero_bmxer]

sorry i had that mixed up with the auto headlamp relay. still didnt find anything today o well i guess everything works so im happy enough.
