I have a new 2003 Tacoma and at 40-50 MPH I get a whistling noice that
sounds like it is coming from the bottom of windshield or behind dask
board. Using duct tape, I taped around hood, windshield, doors, sealed
the complete vent by windshield wipers, and every hole I could find in
fender wells and firewall. Nothing made any difference...still
whistles at me. I took the blower motor out and can hear the noise in
the duct work under the dash. Does anyone have this same problem and
have any idea what it is? I know if I go to dealer they will say they
can't reproduce the problem. They will say what noise...

Please help this whistle is driving me nuts.

Check out www.tacomaterritory.com They have a great forum that should be able to answer that.

Your whisseling noise might be actually a squeek from a vibrating dash. A common problem on Taco's. You need to place a long piece of 3/16 hose in between the windshield and dash. Stuff it in with screwdriver. I'm not sure if I'm remembering the right hose size, what ever fits down in there. Former Toyota tech.

Is it vent register noise? I get some faint whisteling occasionally at high speeds from the fresh air pass through. Do you still get it with the Re-Circulate on and the fan off?
