Well I took the board out today and used a magnifying glass. Couldn't see any broken solder joints. Used continuity tester on the contacts for the defrost button and it worked fine. I did find something else out while I was trying to figure this out. The defroster blows air when the car is not started. Just switch on. When I start the car the defroster stops blowing and I only get air out of the dash and bottom vents. Any Ideas for me to check.
Thanks
