Hey Guys and Gals I,m a new Monte owner and new to the group.I bought a 2001 Monte Carlo LS 4 years ago and finally took it out of storage in July . I was looking for some help trouble shooting a problem. My air or heat only works about 50% of the time,so far I have tried to change the resister which did absolutely nothing any suggestions on the next step I should take.
Thx
Jason

 

Hi Jason and welcome to the forum!!
Make sure to check ALL the fuses/resistors that could be related in all fuse boxes (one each side just inside doors and under hood on passenger side)

 

I checked the ones under the hood but I just figured out there are ones beside the door on a video. I,ll check them tomorrow when I take back the resistor,thanks for the help I need all i can get.Love the 84
