Thread: Heating issue????

Hey everyone, hoping you can help out here. I have a 2004 GP and every spring the car only blows hot air, no matter what I have the temp on. This will last until about May when it has been warm for awhile outside, then it will behave normal blowing cool air when it is supposed to. I have replaced the Thermostat, flushed the cooling, etc. Issue still happens like clockwork every year. Any insight is greatly appreciated as it has been baffling for years.

Thx

That's a good question. Guess I'll have to take her in and get that checked out. Anything else it may be that I can do on my own or look for?
