I own a 1994 Chevy G20 conversion van with 60,000 miles. I have a whistling noise coming out around the heat and air windshield defroster area. It starts and stops when the van is moving, it will slow down and stop as I slow down and stop. It also seems to happen more in the mornings then later in the day (but not always) I have sprayed some rust proofing sealer around the blower motor air cond. housing. I unplugged the blower motor (to be sure it was not going bad). I also thought it may be coming from the passenger vent window. But none of this has worked! PLEASE someone must have had this similar issue and must have something else for me to try before I go any more insane! TIA Greg
