passengers side air condition changes to heat when it rains
When air conditioning is on , when it rains the passenger side heat comes on . It also
seems to lose cfms. Why?
Check for vacume leak,s under dash.
I am not an air conditioning man but I would think if there were a vacuum leak that the system would be the same on both sides. one line controls the dash system vents. I don't see how rain affects it but you may need to have the system recharged but rain doesn't seem to fit the problem.
