My heater has been acting weird lately. I have a remote start and at night I crank the heat all the way up for the next morning when I start it up. I let it run 20-30min in the morning, go out to my car and it's not warm at all. I start driving, and after about 3-5 min it starts blowing warm air, then a few minutes later it's blowing cooler air.
The car is stored in the garage by the way, so it's not nearly as cold as it would be if it were outside all night.
Now it's not winter yet here in MN, but it will be ice cold before I know it, so I am trying to fix the problem now before the harsh cold comes.
Background:
Year: 2002
Engine: 3400
Mileage: 85,000
Any thoughts as to what the problem could be or possible remedy?
Please let me know.
Thanks!
