'02 Monte Carlo LS stock here. I've been living with the 1-5 Fan control only working between 2-4 for a while now, but the refrigerant is in need of a recharge, and I can't do that unless I can max out the fan.

To put it another way, I can only feel air blowing in levels 2, 3, 4. The fan turns off completely at level 1 and 5. The A/C light is still on, and I can feel the residual air from whatever temp I set it at, so at least that works fine.

Any suggestions on how to fix this?

 

i dont know but I'm having similar problems, 1 doesnt work on mine, everything else does

 

yah ive noticed that on quite a few montes ive driven actually im not to sure what thats all about but you should be able to find someone on here that knows something about that cause it seems to be pretty common

 

both of my 01 montes was doing that exact same thing i changed my a/c blower motor and the problem was solved thats a sign that the blower motor is beginning to go out this is common on a lot of GM cars a 97 Grand Prix GT i had last year also had this problem also my cousins 99 buick century had the same problem so try changing the a/c blower motor first then work from there
