Thread: defogger dont work

my defogger in the front just gave up on me, anyone a clue what it could be? my reg heater works, just not my defogger

Most likley a vacuume line somehere, under hood, around battery/ in wiring harness or under air box cracked. Or vacuum line under dash pinched.

Are any of the modes switching? a/c vents and floor heater?

I will assume you only have temperature control, no mode controll whatsoever.

My 98 gtp didn't seem to have the vacuume reservoir, but the line by the battery was very fragile with a few cracks. I ended up making a replacement vacuume line out of 1/8" id brake line, routed beside the transmission select cable in the firewall, reducing the length of the vacuume line by at least 1/2. Use the tubing connectors that were on the stock line, and wrap the brake line in the corrugated plastic loom for concealment (this was on the old line, reuse it.)

hey thanks for the advice, but all it was was the blower motor, go figure)
