Coldest Day of the Year and NO Heat Empty
PostSubject: Coldest Day of the Year and NO Heat   Coldest Day of the Year and NO Heat Icon_minitimeSun Jan 20, 2013 9:42 am

Here's what I've done so far:
Sept 2012
Flushed system
Changed Heater Core
Changed Climate Door

The heat worked great last weekend before I put the car up on stands to fix the front end (tie-rods, drag link, idler arm etc). My buddy came over with his new OBD1/2 reader just to test it out. I think he may have reset the system. What do I need to do to reset the electronic climate control?

thanks

Mark

Remove the fuse for at least one minute, reinsert, then allow it to cycle. Next run the temp up and down to the extremes. It should be ready to go. If not you may have another issue.

Removed the fuse for 15 minutes, plugged it back in, restarted the car, and waited for it to cycle, adjusted the temps and still no heat. I'll inspect the cc door module to make sure it's working, but it's brand new.

So if that checks out, where do I go from there?

Check your hoses and the heater core to determine if they are getting hot. If so, then it is in your heater control system. Probably the temp control system. Someone could have knocked a vacuum line off going to the porting manifold under the dash.

Figured it out. I reached in to make sure the module was working and felt the screws had come undone and it just fell off. Easy fix.... Thanks guys!
