T870 Air Conditioning Control Panel R&R

[TobinG]

I have a 2017 T870 The AC is intermittent. I've changed the cab air filters and cleaned the filter behind the seat. Fan works fine, heat works, but the AC is a sometimes thing. It's been suggested that the control panel, i.e. fan selector, AC on off rocker and temp dial may be the issue.

Anyone have experience Removing and reinstalling this ~2"x 6" panel? I was hoping it would pop off without having to tear the interior out completely, but I don't want to break anything.

Any help appreciated.

The A/C Control Panel pops just out, there are Taps on each side. Use a clip removal Tool or smaller flat head screw driver and it should come right out.
What exactly is the issue? When you run the machine, A/C running Engine running, look on the RH side of the machine, between the Cab and the Frame. You should see a Red light, is it blinking or is it solid on? That's the De-Icing Thermostat which controls the A/C Compressor. If its blinking, look how many time it blinks, like 1-2 or 3 times. If its Solid, that's normal condition.
If that Thermostat is not shutting off the Compressor, most likely your Evaporator will freeze up.
Let me know what you find.
