Has anyone had any problems with their A/C heat control? My A/C was working fine but the last few drives it hasn't worked. Had a look today, the switch I assume seems to either be getting stuck or something inside isn't doing what it should.

Checked the voltage on the the sensor on the drier and it was very low, 0.something, but manipulating the switch it came to life and the fan and A/C started up again. Checked the wiring continuity and all is good.

It's all pointing to the switch, but this is a pretty simple device so am wondering if anything else could be causing it? If not, where can I get a replacement from?

Thanks

Are you sure it's not the relay. Switches usually either work or don't.

I used switches from JJC (they may look a bit Essex for some).

Will get a new relay just in case - switch is probably the wrong description - the rotary thing that controls the temp smile

The temp control only has the one switch contact in it. This may just be dirty from lack of use. Try exercising it several times.

I spent about 15 mins rotating it back and forth, it feels like it is contacting so I'll go and get a new relay and see what happens.

My A.C. started to become less effective over the last few months. So a trip to my A.C. specalist after some testing he indicates that the valve up near the evaporator the one with the thermo couple needed to be adjusted. He asked where it was at and I showed him at which point he gave me a very sad stare and I said no, I do not excpect you to get it out. So now I am faced with removing the valve giving it to him for adjustment and reinstalling it. For those of you in the process of building take a look at where the valve is and consider a acsess panel to get to it. Lee
