I have a 95 Olds Cutlass Supreme 3.1L V6. A couple of days ago, I turned off the vehicle and the HVAC fan stayed on, and stayed on high. I turned the vehicle on again and it stayed on. When I tried to use the controls to lower its fan setting and then turn it off, it continued to run on high. Normally, I can either adjust the fan setting from the steering wheel or the dash board controls. When I use these, it shows on the dash board display that the fan setting is changing, but the fan continues to run on high. I had to pull fuse # 14 to get the fan to shut off. Apparently, there is a short somewhere that continues to supply power to the fan. Anyone have any thoughts on where I should look for this?

 

There is a module on the AC housing about 8 wires & 1 big wire that module goes bad quite often.unplug red wire if it shuts down ITs Bad

 

I appreciate your help! Is this located in the dash or somplace else?
