I am glad I found this forum as well. I also am having this same problem with the rear air, BUT I am having trouble with the front air coming through the defroster as well. We got this repaired a little over a year ago. But the problem returned. The guy that "fixed" it said the part he gave me must have malfunctioned again,but it was no longer under warranty. Anyway, my cousin, who I should have carried it to in the first place, checked under the dash and didn't seem to find any vacuum leaks, so maybe it is the part again. Any suggestions? |
