    Which is the Correct Windshield Wiper Switch?

    The only other switch from Classic Parts, Inc. for my truck is their part # 67-656B "(1978-83) Windshield Wiper Switch". (The only difference is that the one I got says "without Pulse", which is part # 67-656A). And LMC Truck only has one switch (for trucks like mine without cruise control, part...

    Which is the Correct Windshield Wiper Switch?

    This shows the plug in lead at the bottom. Both switches are the same.

    Which is the Correct Windshield Wiper Switch?

    Sorry, should've said the new one is on the right. I can plug in one part of the harness on the plug in lead at the bottom (next picture) but there's no plug in lead on the switch for the other part of the harness (like there is in the picture above on the left switch, half-way up).

    Which is the Correct Windshield Wiper Switch?

    But when I looked at the back of the new switch (waited over 2 weeks for delivery up here in Canada) I saw that a plug in lead is missing! Here's a picture of the back:

    Which is the Correct Windshield Wiper Switch?

    Hi all, 1980 GMC K15. Pretty sure the wipers are running all the time because of a bad windshield wiper dashboard switch. That's because when I hold the switch in just the right spot (near the off position) they turn off. So I ordered the switch on the right in this picture from Classic Parts...

    Dome light

    Well, today the cigarette lighter decided to work, and now the dome light doesn't. Neither does the courtesy light under the dash (also worked yesterday). I think the courtesy light flashed when I manually depressed the drivers open door switch. That gives me something to go on. I think it's...

    Dome light

    I have a 1980 GMC K15 with a single dome light above the rear window. I was getting rid of some non OEM wiring under the dash someone had installed. Now the cigarette lighter doesn't work. Can anyone show me where the orange feed wire plugs into the fuse box? In his April 8 post above Matt69Olds...

    Where do I run antenna wire through firewall?

    Hi, I need to run a radio antenna wire for my forestry road radio from the engine area through the firewall to the cab. I really don't want to drill a new hole in the firewall. Is there an existing hole I can use? The only hole I can see readily is the hole for the clutch pedal, but I don't...

    Outside door handle rod

    I thought this issue couldn't be more painful than the install I went through. Thanks for the update Mr. Super Moderator.

    Outside door handle rod

    So I dispensed with the Dorman clip and tried a different approach. After great difficulty I managed to get the end of the rod into the bottom hole of the lock mechaism. Then I was able to get a bailing wire into the top hole and thread it around the back of the stock of the lock mechaism that...

    Outside door handle rod

    I tried using the white clip (top row, middle), but I think the end is too large to insert into the bottom hole in the lock mechanism. I also tried the black clip but I think it was too large also. This picture shows the white clip installed before insertion into the door.

    Outside door handle rod

    FYI everyone, I finished the job. Don't like the Mickey Mouse way I did it but I couldn't restore the factory set up. I couldn't get the clip (illustrated above from 1980 GMC Service Manual page 2D-15, Fig. 2D-37 in yellow) anywhere I tried. I tried using the Dorman kit 75450 as ajd89 suggested...

    1980 K15 Step Bumper brackets and braces

    Hi 86454k30, thanks for the quick reply. So, I can't use the aftermarket mount with my OEM bumper? Or is it that I can use the aftermarket mount with my OEM bumper but I don't need the brace?

    Power Windows Troubleshooting Info

    Thanks so much C10MixMaster, you've provided a LOT of great info. I appreciate it. Unfortunately, I still have more questions (sorry!) 1) Where is the circuit breaker on your 77? On the 2nd page of this thread (post #20, Jul 6, 2013 by HotRodPC) there is an attachment "FuseBox85K1500.jpg". It...

    1980 K15 Step Bumper brackets and braces

    Hello all, thanks in advance for your help! I have a step bumper on my K15 and it is barely hanging on because it is only bolted to the angle brackets that attach to the bumper near the ends of the bumper. There are supposed to be additional brackets with one end that bolt to the frame and the...

    Power Windows Troubleshooting Info

    Hi all, I did a stupid with my power windows. I have a 1980 GMC K15 (std cab) and the power windows do not operate, either from using the driver's side switch or passenger. I pulled off the driver's door panel and the 6 wires that go to the power window switch pretty much fell out, so I think...

    Outside door handle rod

    Hi ajd89, thanks for suggesting the Dorman product. I don't know if one of those would work. I'd hate to go through the trouble of snapping one into place only to discover the rod won't fit in it or align to it or something. I don't mind trying, but what if I have a lot of trouble getting it out...

    Outside door handle rod

    Hi all, I just got off the phone with LMC. They confirmed they do not have the clip for the outside door handle rod. The illustration on page 68 of the 2021 Catalog (CC. 103) shows clips for the inside door handle rod (26, 27, 29). They confirmed these clips are not for the outside door handle...

    Outside door handle rod

    Hi C10MixMaster, thanks so much for the illustration and your answer about the upper and lower holes. Makes sense. The LMC link you provided refers to the same page I mentioned in my reply to Snoots above. I'll have to call LMC for clarification. I need them to confirm they have the clip.
