Tody I had reason to pull the underdash panels (on passenger side which are held in by velcro). Just looking to make sure wires and ducting were all in proper place. Then I noticed the return air grill used for both the A/C and dash heater. WIth the velcroed panels in their normal place, there is no way for the return air fron the coach to reach the return air grill and on into the heater/ac system. Now I am sure that some of the return air finds its way thru cracks and poorly fitting dash parts. But hey, this must be a mistake. Has any one else run accross this situation. If I happened to be using outside air, no problem, but return air only and I would be having little or no air return.
