Hello - I have an issue I was hoping someone has dealt with. When the air conditioning or heat is on the round gauge to control how strong you want it to blow out of the vents (labeled 1,2,3 or 4) is not working. The center gauge - images below
When I turn the gauge from "off" to "on" (shown as 2 on the image below) the light comes on on the gauge to the left of it and I can hear a "click" coming from the engine.
I tried replacing several fuses to see if that was the problem, and didn't fix the problem.
I replaced:
Fuse 22 - Mass air flow sensor, purge solenoid
Fuse 48 - air conditioning clutch
Fuse 59 - climate control
Fuse 82 - climate contol fan
I also saw there is a "Relay" marked "87" called "Heating, Ventilation, and Air conditioning - anyone ever have to replace one of these - could that be it?
Also wanted to mention the A/C and heat are working, when you switch to either you can feel hot or cold coming out of the vents - just very lightly.
Thanks for any help or suggestion - Happy New Year!
Eric
