I'd check the printed circuit very carefully. Pay particular attention to the "ears" at the end of traces where they contact the main connector. A study of the printed circuit diagram makes me suspect that if the top two "ears" on the side where you see the 2nd wire down heading directly to...

Thank you. It would seem that it didn't make into all of the 79s. Perhaps color mattered?

I haven't found the build sheet. It has everything else that came with the convenience group. It has the CB, glass tops and every factory option except the spoilers.

Since Road and Track made specific mention of the lighted passenger side mirror in their scathing review of the '79 it must have been available. I have a very late production L82 '79 (the Jimmy Carter 85 mph speedo) with every option save the spoilers, low mileage and in very good and highly...

:thumb EXACTLY!

The wiring for the bulb is in the switch connector (the top one if you have delay wipers). There is no additional wiring for the light--you just need a twist-in socket.

Upon purchase both headlamps opened and closed (but the right was quite slow). Then the right stopped opening, next the left. When I removed the actuators BOTH had the front seal sucked into the actuator body. I tested with about 20" mercury vacuum on the bench; both seemed OK after...

'79 with delay relay/module in the center console. I'm loosing patience with my wipers. Problem: Delay does not function--runs constantly at low speed in the "delay" switch position. Otherwise wipers and washers work exactly as specified. My original wiper switch had a problem in the...

After getting everything cleaned and lubricated I tried the actuators--one sucked the front seal into the body on the 2nd opening and the other now showed a very slow leak in the main diaphragm. Ordered replacements--about the first time I've ever bought non-OEM when such is available but the...

Yes, the light wiring is in one of the switch connectors. You just need a twist-in bulb holder like in the instrument cluster. The proper bulb is #194 (2 lux)

Working on a new-to-me '79 with low miles but uncertain history. I'm 100% certain that the actuators have been removed before but do not know if they are original or repaired. The main seal on the operator side of both of the actuators was sucked into the body of the actuator. Both that...

Recently replaced my carpet throughout. It came from Zip Corvette. For the compartment doors, center tunnel sides, center console sides, kick panels and seat backs, I used brush-on contact cement on both the carpet AND the piece with a laminate roller for pressure. (The laminate roller is no...

Antz81: I forgot to mention that the reason I jumped between the orange and white wires at the controller was to try to force the controller into pulse mode. I also tried it with a 100 ohm resistor. According to both the schematic and circuit explanation it should have gone into pulse mode no...

Thanks for confirming my suspicions. Yes, by "pulse" I mean "delay" or "intermittent". The wipers are the last of my electrical problems and I'll be VERY glad when they're all fixed. For a car with only 50k on the clock and excellent mechanical and cosmetic condition it sure had a lot of...

1979 (pulse control/relay in center console). Problem: wipers run constantly in "pulse" position. Low, high, mist and wash all working properly. Pressing "wash" momentarily with the switch in the "off" position always results in two sweeps of the wipers, not the "three to five" sweeps stated...

Thank you very much! All I could find before was the "without CB".

New (to me) '79 with some electrical problems. Found antenna as one of the problems in the fuse-removed courtesy circuit--it was constantly trying to go down and would not kick the down limit switch. Up worked fine--a couple times--then the cable broke. I'm guessing that the cable was...

The horn problem was not fun... Finally traced to no +12V at the horn relay. Stop/Flash fuse OK and stop/flash circuits working. I'm very particular about wiring but no freaking way was I going to remove the fuse box so I pulled a on the power lead to the horn relay connector to get a bit of...

Thanks. I finally found the release lever/spring at the bottom of the cable connection this morning. Hadn't had a chance yet to reply as I'm now busy chasing down a problem with the horns.

'79 Working on electrical problems and cleaning along the way. How do I disconnect the speedo cable at the cluster? Dash pad, center console, center cluster all removed. Service manual no help--it just says "disconnect". Thanks!
