Hi guys. My ram 1500 will not switch to defrost. I can only get air flow through dash vents and floor. Air will come out of vents full power when on defrost.
It has auto temp control.
Also, it began to act strange a couple of months ago. When I start vehicle, the air conditioning will blow full power then shut off for approximately 3-5 seconds and restart. I never noticed it doing this before. Maybe both problems are related. Any idea what may cause this condition? Thanks.
