1979 Chevy Truck - The Fun Stuff - Tech

We used a crush-type terminal connector to repair the broken cable. Notice the bracket that holds the cable in place is adjustable up and down for tension.

We moved the cable up and down until the needle lined up, and then we tightened it down.

While the dash cluster was disassembled, it was the perfect time to gain access to detail the areas normally inaccessible. We found Meguiar's Ultimate Quik Detailer to be the perfect product to restore the appearance as new.

To replace the original fan switch, it wasn't necessary to completely remove the switch panel.

The switch panel was tilted outward enough to allow access to the two screws retaining the switch, and then we removed it.

To insure a long life of trouble-free service, we coated the terminals on the switch with diekectric grease.

That completed, we replaced the plug onto the new switch and reattached it to the switch panel.

Last on our list was to replace the dimmer switch. We determined the original switch was bad by jumping 12 volts to the high and low beams to establish they worked.

Some good clues that the dimmer switch needed to be replaced were the burnt wires and a melted plug.
