I have just been going with the suggestion made by another member on how he was dealing with it. In order to change the temp, I turn off the AC, wait for the vacuum to release on the blend door mechanism, change to the new temp, then turn AC back on. This works perfectly although it is a hassle.
With key on run, I selected defrost/floor/etc while listening to doors open/close to make sure things are moving as expected for air flow. Then starting engine with control turned to Off. Putting temp control all the way to coldest then turn to A/C or Max A/c. seems to work. Will probably have to replace temp control at some point though.

Bypass temperature control switch
Hello!
Wondering if it is possible to bypass the temperature control switch on my 1998 F150. I realize it is a potentiometer/rheostat type switch. Just wanting to know if there is a way to bypass this. I can't get any heat right now and the switch feels awfully loose (no resistance).
Thanks in advance for any help offered!
