Hey all, I have a '91 ext cab 4x4 with a 350.
My wipers don't work, and I can't control the
heat. When I turn on the wipers, they don't
even budge, and I hear a sound kind of like a
kazoo, or one of those party favors, only not
very loud. It's comming from behind the dash.
The only way I can control the amount of heat
I get is by taking off the cover on the heater core,
reach up and push on the flap as I push the
button on my dash. Could these be related
problems?? I've been told that both are
vaccum controled. Thanks for the help!
