A/C works but no temperature control.

Posted June 26, 200618 yr

I can move all the heater control buttons except the temperature adjust, it seems to be spring loaded to return to center. Pleasea advise.

Thanks

S.B.

I would venture to say that the cable is probably froze up. Might try spraying some lubricant into the end of the cable jacket. Will probably take several sessions to free it up. Might also be the valve itself.....

Thanks for the info - it was a combination problem as is so often the case.

The linkage was in need of some lubricant (which it got (spray ) but the cable was kinked as well (probably due to the resistance from the linkage).

The cable was the major nuisance to fix - with out removing the dash and/or heater control unit. I applied some Newfoundland mechanical CDF (common dog F--k): I straighted the cable as best as I could and fabricated a sleeve from a piece of antennae section (replaced during a radio repair) and fit it to the wire/controller end. That contains the kink and acts as a telescoping guide.

Main thing - it works and I can get cold air again Now to rerpair the A/C.
