Looks like it should be behind the glove box, but I can't find it. Anyone have any more info, 1995 Accord.

 

I think that it is on top of the evaporator.

 

well It's actually a thermistor/ SCR set up.....Should be located on top of the evap box, with 2 thin wires running around the drivers side of evap box.
Here's 2 pics that explain testing......FWIW I 've never seen one go bad.

 

Thanks, I'll see if I can find it. It's the next step in testing my ac, if I ground one of the wires at the pressure switch my a/c works correctly, so it is either the thermo switch or the ecu not supplying ground to the circuit.

 

I was sent the wrong schematic, now have the right one and did the test, my thermo is bad, bypassed it and it ran down to 29 degrees out the vent and I shut it down.

So now, can it be easily replaced? looks like the box has to come apart, can the bottom be dropped in the car?

 

Well, finally messed with it again, the thermo switch was bad, and also a trace on the heater switch circuit board was lifted and fried. I soldered in a jumper for the board for now, and a new thermo switch, and all is good.

 

I'm pretty sure my ac thermo switch is out on my '93 accord wagon. Do I access it by pulling the glove box or blower motor out or can I access it via the driver side? Thanks
