Yours might benefit from such a service. I dont remember the specifics of what was going on with the unit in the album but I do know that when it was installed it worked well. I do recall it having a few cold solder joints.

Additionally, the outdoor temperature sensor is unrelated to the climate control system. The only temperature sensors that the push button unit care about are the evaporator temp sensor and the cabin temp sensor
The 1987 and later models can sense issues and will click the blower motor on and off until it senses the issue is resolved. This comes from the FSM.

I have to disagree with you on the outside temperature sensor. The ambient temperature sensor is only for display but according to the FSM the outdoor temperature sensor is used by the push button unit.

I was trying to take mine apart to replace the caps and reflow but I cannot seem to get the wheel off. How did you do that?

Attached is FSM stating the diagnostic feature.

Thanks for the help.
