Question about Cars & Trucks
Had replaced the alternator a few years ago and accidentally shorted something which caysed the radio and heater not to function properly. The radio will power on (the light anyways, but no display or sound and the heater blower speed wont work and was bypassed with a resistor switch? I think that's what it is. It has 2 post on the back and what looks like a long screw. The front of the knob has a brown knob that says "HEAT" and has 3 settings, off low and high. When on low the knob would get really hot and it actually shorted out I think but when on high it doesn't get hot. I need to find a switch like that or one similar that can do the job. The directional flow on the console works though (defrost, floor boards, et cetera) I would appreciate any thoughts and feedback!
TRY RADIO SHACK. MOST PEOPLE WHO BUILD PROJECTS LIKE SWITCHES GO TO RADIO SHACK. I HAD A SIMILAR PROBLEM AND THAT WORKED FOR ME. OR IF YOU WANT THE EXACT SWITCH THAT YOU HAD TRY A JUNK YARD LIKE LKQ, (352) 746-3011 IS THE CUSTOMER SERVICE NUMBER.

You will have to go back to the mechanic or shop that supplied it or take it out and start what may be a long and unsuccessful search at many electricla and electonics supply shops.

After two summers of sweating under the sun, it's fixed!!! There were two wires which looked like ground wires right above the glove box. One of the two wires was almost totally severed due to an overstuffed glove box. I guess every time I open and close the glove box, paperwork in the glove box push the wire up and down. It's like bending the wire back and fourth. Over time the 2-3 mm thick wires slowly sever. Upon inspection, my wires only had 3 strands holding it together which explains the fan staying on the low position due to slow ground. I re-attached the wires and soldered them back into place. Now my AC works like new - thanks to Mathew the Mechanic.. Thank you for asking. I really hope this posting helps someone with the same unique problem.

These trucks have a problem where moisture builds up in the heater box then freezes. When this freezes and you change your heater settings it breaks the shaft for the blend door. If this is what happened you should be able to look under the dash above and to the right of the gas pedal and you will see two vaccuum accuators one of them you should be able to wiggle around the linkage if it is broke. To fix this you need to remove the entire dash to get the heater box out which involves discharging the AC and draining the coolant because the heater core and evaporator come out. Please rate.
