Hello all, I'm new to the forum. I own a 2000 Monte Carlo the Canadian Made model. I've owned it for 3 years now and have only made 2 repairs to it, fuel pump and fans. I love my car. I'm constantly getting complimented on it.
So my question about air conditioning is ,
The switch has only worked on 5 all summer. But now 5 has gone out too. I'm dying it's a black car and I still need to replace the window motor on drivers door and I live in Cali where it's been 100's or 90's so I am so sweltering. I found where this problem is the resistor under dash behind the blower motor. My question is is are there any other things it could be besides the resistor?

 

most likely its the resistor, pretty common issue on gm cars, mine went out last summer....pain in the *** to get at but 99 % chance that's yer problem.
