Hello all~!

I have a 1997 Audi A4 1.8T 5spd and since last summer, I've been experiencing a weird AC problem.

I just ignored it til yesterday when it reached over 90 haha.

My AC system blows out cold air, when I'm driving

But when the car comes to a stop/idles/gets stuck in traffic, the rpm goes up a little (like 400?) and then it starts to blow out moist and hot air, which literally killed me last night in the city haha.

Based on my symptom, can you guys possibly tell me what could've gone wrong?

Your problem is your AC fan isn't switching on and pulling the air through the condensor. Check your fuses, then turn the car on, turn the A/C ALL the way up and stand outside the car watching the fan on the passenger side. once the idle increases the fan should kick on, if not, that's your problem...
