I am new to this board and this is my first post. I am looking for a little help with the issues I am having. I have a 2001 Alero. It is a 4-cylinder automatic. I bought this car new, and have driven it ever since then. It currently has approximately 88k miles on it. Here is a list of issues that I am having with the car:

- AC doesn't seem to kick in until I move the knob to the third position.
- Rear defroster doesn't seem to work anymore.
- My turn signals go crazy (I call it machine gun turn signals) and sometimes do not work at all. This only happens sometimes. Never really consistent.
- Sometimes when I am backing up, the lights on my dash come on (abs off, trac off, service vehicle soon). I can turn off the car and restart it and they will disappear.
- Lately, my car has been idling rather low. It seems to be off and on. When I start the car and leave it in park, it idles at approx. 1000 rpm's. Then sometimes when I am driving and come to a stop at a light or sign, it may go down and idle at 500 rpm's. When I proceed to take off from the light it seems to be a little sluggish and then jerks and pops into gear. I changed the air filter last night, thinking that maybe not enough air was getting to the engine, but it seems to still be happening.
- My radio gets horrible signal. I hardly get any stations. When I use the seek function, it finds nothing.
- My service engine soon light comes on from time to time. I took it by Advanced Auto Parts and they ran the handheld on it and said it was a "Pedal Position Sensor: Bad Input"....not sure exactly what the heck this means.

If anyone has any input that would be great. I am going to start to try to fix these little issues. All have been happening for a year or so, besides the idling problem which is rather recent. Thanks for the help!
