while going down the road with the airconditioner or just the panel it some times switches to the defrost vents... at random...i have to switch it back to off and on a couple times to get it back to the panel...

You think this might be a loss of vacume? It has to have somthing to do with vacume i suspect...

 

Please go to the HVAC forum and spend a few minutes reading the posts....

If you need them, SEARCH keywords "+defrost +vacuum" will help.
