My Climate Control unit has had issues for some time now. When I start the car the CCU has no display the buttons do nothing what so ever. I had BrianK survice my Climate Control Unit. It seemed like it worked for a week then one day started the car and same thing no display no lights. the only change after the service is now sometimes the air blows out full blast. I checked the pins(ones the service manual told me to check) and got battery voltage where I needed it and continuity(sp) on the pins I needed. I am down to trying to get a known working CCU to check to see if its the car or the unit causing my woes.
(edit)The problem is intermittant. Like a flip of a coin sometimes it works like normal other times it doesn't. My question is could a fuse or Relay(main relay) cause these symptoms? I have waited for the problem to occur and immiediately with the car on unplug the unit and check the pins, so I don't think the issue lies in the wires.
