pamike Posted November 12, 2009 Share Posted November 12, 2009 when i push the buttons to change from one setting to another for example defrost to vent nothing happens. i searched and found that the soldered connections on the back of the unit can cause this problem. but when i press the defrost or defrost/heat button the fans turn on. and when any button is pressed i can hear a clicking like a relay from the fuse box area. does this mean that my controls are working and my problem is elsewhere or can the connections still be the problem. because this makes my think my buttons are working. anyone have any ideas.

gbianchi Posted November 12, 2009 Share Posted November 12, 2009 buttons may be working to engage ac comp on def/defheat mode which will turn on the fans, but not working to change air flow direction, thump the dash above control to see if you can get direction change if so then you'll need to pull control and resoder conectors, its only going to get worse! Sorry, been there done that............G Link to comment Share on other sites More sharing options...
pamike Posted November 13, 2009 Author Share Posted November 13, 2009 i hit the top of the dash and they all worked for about 5 minutes and then i couldn't get them to work again. Link to comment Share on other sites More sharing options...

Legacy777 Posted November 13, 2009 Share Posted November 13, 2009 Yeah, it's gotta be the controls. Here's pics from my resoldering job. http://www.main.experiencetherave.com/subaru/images/hvac/ Link to comment Share on other sites More sharing options...
pamike Posted November 15, 2009 Author Share Posted November 15, 2009 i pulled the control unit out today and did find alot of connections that needed resoldered. it seems to be working good so far but i'll give it some time and see what happens before i say it's finally fixed.

gbianchi Posted November 17, 2009 Share Posted November 17, 2009 I drove mine an entire winter with the dash sort of apart till I was sure it was fixed. I also picked up a spare control at the jy and resoldered it ahead of time, spare parts are a gold mine............G Link to comment Share on other sites More sharing options...
