Vacuum problem

Postby BFVSFOREVER » Tue Dec 19, 2017 7:08 pm

My 2002 Crew Cab 4X4 has a problem I don't understand. My Check Engine Light came on, AutoZone tester say's it is the Throttle Body. At about the same time my Heater / Air Conditioning Selector quit working, Air blowing from all outlets at once. Would a bad hose cause this. The truck has less than 100,000 on it and I can't believe that throttle body shaft is worn out. Any help is greatly appreciated.

Check the vacuum hoses for dry rot behind the brake booster going to the vacuum canister in the driver side fenderwell. Make sure the hose is attached to the nipple just under the fender lip.
