Got a bit of a whistle/whine/howl behind the dash of my VP. It's only seemed to happen since the weather has started to cool down.
If I accelerate, then come off the pedal, It will whistle behind the dash - even with the fan off.
Anyone know what could be going on?
Vacuum leak maybe? Have you taken the dash apart recently and removed the A/C controls? If so you might not have put the hoses back on enough and they could have come off. I would check out all the Hoses before anything else but that's just me
