ACC Control - Relays?
 

Hi All....

I have an 83 SD and the climate control is acting up. I pulled it and soldered any cracked joints under the cover...but at times while it is running the fan will just quit. If I tap the underside of the case with something....it starts up again.

I noticed little relays on the board. I wonder if they are sticking and in need of some lube or cleaning?

Any thoughts appreciated.
