Hello. If you push the AUTO and OFF buttons simultaneously on your ACC module (air conditioning unit), your a/c system will run an approximate 30-45 sec. diagnostic test on the system's components. Most likely your code will read 1...............08 - this is a common problem occuring with the Saab climate control system. If your code does indeed read this - be prepared for what the dealer will try to hit you with for repair cost - usually over $2000. HOWEVER!
It takes a small amount of time - 2 to 3 hours - and about $70 in parts from a Saab dealer and you can easily remedy this common nuisance. The parts you will need to restore heat flow will be a blend door shaft sleeve and a stopper arm to fit it into for the blend door motor. The part numbers are, respectively, 12765865 (sleeve), and 5334701 (stopper arm). Here is an excellent DIY guide for the repair >>>
It does not quite say it in the guide, but you will need to take off the bottom of the driver side dash and also take off the diagnostic terminal from the dash and kind of move it out of the way. You will see the elbow and blend door motor, and will require 6, 6 mm screws to be removed (or a phillips head screwdriver - if you're bloody brilliant, and I highly recommend getting a stubby screwdriver for these!) Other than that, the manual should tell you the rest. I actually just finished my repair with it today and I've restored my heat at only the cost of the $65 for the parts....isn't it grand to save $2000?
Before you purchase these parts and progress with this repair, you should first check to make sure that it is not just simply the blend door motor which has gone out over time. Simply follow the steps up to taking off the dash liner and remove the HVAC floor elbow. If you see that the yellow shaft is still intact and has not broken, then try to reach up and turn on your heat and watch for the stopper arm to move. If it does not move and you have energized your heating system - then the blend door motor is the culprit of your problems and is a MUCH easier fix than the one listed above. I would save yourself the money and get a used part - even if you have to do it again in the future. The new buggers are about $350 or $400 ... ouch. OH, and all you need to do replace the motor is take out the elbow and blend door motor screws, and CAREFULLY slide the motor out, as you do not want to break the blend door shaft. Then just reverse the process and you're done in no time.
Hope this was helpful, and drop me a line @ email@example.com to let me know if that was a solution for you!
