'66 Light Switch

[Mark W.]

When turning the headlights on, the taillights won't come on about half the time. The headlights come on all the time. If I wiggle the switch, the taillights come on. Is the switch repairable or should I just spring for a new one?

Go for a new one!!!! They aren't that expensive. Don't forget...to get the knob off you must depress a small button on the switch assy to release the knob and shaft. It doesn't unscrew.....

Mark - I agree with Steve; but the "original" P/N 1995131 swithch used from 1964-1966 is getting more difficult to come by so if you're looking for an NOS Delco-Remy part you might find it more pricey than a replacement from another source. It's my understanding that NAPA has a functional service replacement that is acceptable (please check it out and see if it meets you're expectations) and that it's what you need specifically as far as function with the parking lights.

A replacement headlight switch is available from GM under GM #1995179. This part currently GM lists for $28.42. This is not the original part number for the switch used in your car, but it is a functional replacement. Given its location behind the dash, I wouldn't think that any configuration differences would be much of an issue, but I'd save the original switch in any case.

The above-referenced 64-67 replacement headlamp switch is the ONLY headlamp switch still available from GM for any 53-82 Corvette. For how much longer, who knows?

If You Have The Patience.........

and skill, it is not hard to disassemble and clean/relubricate. Bend back the metal retaining tabs, being careful not to crack the Bakelite housing. After tabs are released, SLOWLY separate back cover(be careful of the potentiometer for the dash dimmer/courtesy lights), while noting the orientation of the internal parts. You will probably find a dirty contact or two--lightly clean them all with a points file, lube the friction surfaces, and reassemble.
It is also possible to remove the switch, and while giving it a good bath of carbon tetrachloride, work the switch in and out. This doesn't always work, but is worth a try if you are timid about opening up the switch.

Joe,
Is this the switch that turns OFF the front parking lights when the headlights come on?

Re: If You Have The Patience.........

Thanks for all the suggestions. I forgot to mention that my '66 is a driver, so functionality is more important than originality, although I try to keep it as close to original as possible and I keep everything I remove/replace.
