replace the hot water valve and the recir diaphram using the link I posted. You should be comfortable even if you don't care about AC. |
ok, thanks. i still haven't tried that test yet, but i will tomorrow. one more question in the meantime... i seem to be having relay issues in other areas of the car...any chance this heat issue could simply be a bad relay? I see relay XVIII is for "Cooling air flap adjustment." And relay X is for "fresh air blower." If either of those were bad, could that cause my constant hot air? Or are those completely unrelated to this problem?
