HVAC fan issues
Okay my HVAC fan speed control seems to change speed on it's own, not at every speed level, but at a couple of them. It will speed up and slow down. If I jiggle the rotary dial I can get it to change speeds as well. I have removed the unit and done the repair suggested by CL770. I have also replaced the fan motor resistor. Neither fixed the issue. Any other ideas ? Is there a way to clean the rotary switch ? :confused:

Mine does the same thing occasionally, but not enough to be concerned yet. I spin the rotary switch up and down a few times and it is ok for some time. I am sure it will get worse with time. Please keep us informed of your findings.
Thanks, James |

Re: HVAC fan issues
I see some online sellers claim the HVAC control unit they have will only work in an automatic transmission car. Looking in the Crossfire parts catalog, I only see on part number listed for this part. Is there a different part number for manual cars?

Re: HVAC fan issues
no reason why there would be two different parts.
