My interior heating and cooling started going in and out. During the winter the heat would sometimes get cold. during the summer the a/c would get hot. This was last year. I went about 5 months w/o driving it. now the a/c does not work at all. Commpressor will not kick on. Here is what I've replace/checked.
Replaced. INterior control panel $ouch$, Low side switch, High side switch.
Checked freon level with line sets. W/o commpressor on. lowside reads high. hight side reads inrange.
When temp control is on max heat the temp door (under dash) turns to max heat. One click back is 82 degrees, the temp door turns completely back to cold side.
Over head temp sensor no longer buzzes.
WTH!!
