The "Prrrrrr" noise
I noticed a very faint noise coming from the truck area, while iddling in the garage. It is a "prrrrrrrr" that lasts for about 5 seconds then goes away for 10 seconds and returns. It could be the compressor for the seat cushions, and if it is, could it point to an air leak, so the compressor is trying to maintain a minimum line pressure? Any ideas? BTW the cushion controls by each front seat work well. Thanks folks.

Its not a compressor , this is the Vacuum pump working .. it is not in the trunk , it is under the rear seat passenger side next to the Battery ...
