Got all the lights working but the glove box clock. Now when I turn on the instrument panel light switch within seconds it feels like it is on fire. Is the switch going bad or is there another issue. If it is the switch were can I get one, I don't see them in any catalogs

Is there a fuse ahead of the switch that gets hot? If the switch gets hot because of too heavy load (short?) it should blow a reasonably sized fuse. If it is drawing a normal amount of current, I would think there is a loose connection in the switch causing the heat build-up. If you don't have an amp meter, splice a fuse holder in with the correct fuse.

I think the switch itself may be bad. If I wiggle the knob, lights go off and on

It sounds like you have a short somewhere in the wire to the clock light, or in the clock light bulb socket, assembly. Take it out, with it's wire, and test it with jumper wires on your battery; or use jumpers from the socket to ground, and from the wire end to power. If it lights, examine the wire for bad insulation and or bare spots, and repair as necessary. If there are none, replace the dimmer switch, or just connect the output wire on it to the input.You'll have a clock light, but always bright on the clock light and all panel lights.

If you wiggle it on the lights go off and on, the dimmer swich is bad, or the wire connections on it are likely loose. If the connections are tight, and it still only works when you wiggle it Take the two wires off and connect them together. Problem solved! You just won't be able to dim the panel lights, which shouldn't be a problem. By the way, that switch is easy to remove- just take the two screws at the bottom of the dash below it out. DON'T FORGET!! Disconnect the hot (-) battery terminal FIRST to prevent any SHORTS!!!

Sorry guys, this is a 1936 club cab. It's the dimmer switch that I am working on. It has two bullet connections on the back and they seem snug.Where can I get a switch, haven't found any in the catalogs for a 36

These are 1 of the hardest things to find and command top prices when found. It is NOT a dimmer switch. Just an on & off switch. Their are 2 diff. ones from 34 to 39 ithink. 1 the lites are ON in the out position and the other one has the lites on in the IN position. Finding a good one is almost impossible, GOOD LUCK. ken ct.

Bob56 - so that no one gets confused, please clarify whether you are referring to the 'on/off' switch on the floor that looks and functions like a classic dimmer switch, or to an actual dimmer switch itself that someone before you may have installed. Thanks - this has kind of gone around the horn a bit. I looked on ebay today just to see and thought I saw a couple of these listed, but I am not nearly as conversant and knowledgeable on this model and year as you and ken. Have a look - perhaps what you are looking for is there.
