OK - I have successfully removed my entire dash, replaced the leaking heater o rings and am now attempting to figure out what's going on with the blend motors. My initial idea was to just buy new ones and replace - but I thought first I would see what I could find out about the old ones. So I took them apart and found the gears to be perfect on all three - and I checked the little flat thingys inside that sometimes get rounded and create a short - they were nice and flat. So I put the control unit back in place along with the airbag and instrument cluster and plugged in the motors to just see if one of them didn't respond to the control unit.
None of them did! So my question is - shouldn't I have been able to see all of the motors turning their little spindles as I changed the settings on the control unit? Did they somehow know they weren't screwed in to the flaps? Is this a sign that my control unit is no good? I noticed the book symbol remained - even though the motors were free to turn. Is there another test that would tell me that the motors are indeed the problem? I would hate to replace them if they are perfectly good - although I suppose at 130+K I should replace them anyway...
Any thoughts would be appreciated! Thanks.
