problem with heating
 Total experience was excellent for the first 2 months, at which time the heating for the floor stopped working; the face and defroster are okay.  It was in the shop twice and was told that nothing is wrong; they put it up to 90 and it seemed to be okay; but the next time we drove, it was still cold!  Where do I turn now?
