Hey everybody, A/C question for you.

The problem: A/C turns itself off (condenser fan and clutch off)-or it will turn on for 2 seconds then the fan will spin off and clutch disengage

What I have checked: A/C switch (jumped it), relays and fuses, climate control inside unit, also had a leak test last year so I should have enough refrigerant pressure

When it does work: When I hold down the recirculate button on the climate control-comes in cold with condenser fan on and clutch engaged. At night it will usually work as well or when I first start up the car (works for a few minutes, when it's really hot out it doesn't work)

I think there may be a short? Where could I find the A/C thermostat so I could check that and the switch that comes off that? If I use a volt meter to test it, where should I start? Any ideas would help!

Specs: 1994 Honda Civic DX stock.

Thanks!

 

I am wondering if there is a problem in the AC control panel on the dash, I know some Acuras had this issue.

When you hit the AC button doe sit stay lit?

A simple check, on top of the dryer there is a switch, unplug it and put an ohm meter to it (one lead to each post) and see if it reads 00

 

Had a ground come loose and it did that.

 

motegicivic, The light does stay on when it is switched in, if I mash it down farther it stays on while I keep holding it, but otherwise it wants to turn off if its really hot out, tonight it was working fine, and I took apart the climate control unit and I didn't see anything wrong with switch compared to the other ones on the panel. I will try to check that, and I am trying to check the grounds but don't know how many ground wires there are?

 

Sounds like a bad heater control panel.

A Blu/Red wire runs from the thermostat to the heater control panel. If you ground this wire at the rear of the heater control panel, does the A/C now work without shutting off? If so, replace the heater control panel.
