Kipper Posted September 27, 2009 Share Posted September 27, 2009 I have a '93 subaru legacy. I believe I have a bad electrical connection somewhere because the vent/heater blower motor will not work..At first the blower would randomly come on when the car was either warmer or when I hit a pump in the in road..Now it wont even randomly come on so it leads me to believe that this is a bad wire somewhere or a connection. could be a loose wire on the fan speed which or something...does anybody have any suggestions before I rip the dash apart?

Bdubs Posted September 27, 2009 Share Posted September 27, 2009 When you select the buttons on the HVAC unit, do the lights come on? If not, it's within that unit itself. The solders corrode over the years, and it causes the controls to do wacky things. Link to comment Share on other sites More sharing options...
Kipper Posted September 27, 2009 Author Share Posted September 27, 2009 the 8 button switches above the cup holder? For awhile only some of them came on. Not all of them come on now...Would you suggest taking the dash apart and re soldering?? Link to comment Share on other sites More sharing options...
Bdubs Posted September 27, 2009 Share Posted September 27, 2009 Yeah, under each button is an amberish colored light. They should illuminate when you push them in, and you will hear the fan kick on. In some cases, the wires are loose or the solder has cracked. I do suggest taking it out and at least just fiddling with the main wire harness. Sometimes just removing it and plugging it back in solves the problem. While you have it out, you can inspect for any cracks in the solders. Fortunately, taking it out is rather simple. You just have to take out a few of the trim rings around the radio and I believe the main cluster to access all the screws. It's not all that complicated, and all you need are a couple different length phillps' screwdrivers. Link to comment Share on other sites More sharing options...
