So an odd issue with my 2-door 92 DX. The radiator fans will kick on and off like normal in heat cycles, but they are not engaging when you turn the A/C/ on. Would that be the switch at the thermostat housing going bad??

 

Nope. The switch is working because the fans kick on when your coolant hits the proper temperature.

Is your a/c compressor working? I'd probably start testing at the a/c diode as that provides a one-way path to ground on the green wire when you turn on the a/c.

 

I do feel a slight "bump" when I turn the compressor on, yeah.

 

where is that diode located?

 

It is #2 on the diagram below, so near the condenser relay. #3 look like a rubber cap to protect it. It should have 2 blue wires going to it.

Please verify, because the shop manual I'm using is for non-US accords.
