Hello,

My 1985 GMC K1500 Sierra Classic came with a clock in the lower left hand corner of the dash. Anybody know where I can get it replaced and/or repaired. It started with intermittent operation and now only works if I tap on it. Even then it stops sometime later. I'd like to keep it stock if I can. LMC truck does not list one.

thanks in advance...

LMC does have them now... I think it was $99.00 I saw them last night in my new lmc book.
 
Here'e a picture that I promised, also a picture of a factory radio that also works and is available:whistle:

Sounds like way more than they are worth but I will check them out...thank you.

Catalog shows it fits 73-79 (item #36-1983) so I called them hoping for a misprint. No luck...only fits those years.

Thats pretty cool that LMC has that clock available. Has anyone ever added this mod to a non-clock optioned rig? Do you run a wire directly to the battery or do you patch it into something pre-existing.

Not a great sign when a factory optioned clock owner unhooks it though. :rolleyes:

Is that why you don't see many factory clocks if it drains the battery? Why would they even offer the option if it is detrimental to the overall dependability of the truck?
 
I have seen lots of these clocks in the junkyard while searching for bezel & dash stuff. I keep loosing the little knob , I need to go back & get one.
 
I need a new second hand for mine, it got broke years ago, but the clock still works.
 
I had a brand new in the GM box one I just put in my truck that I never could sell. I also have good used one if anyone is interested.

If it works at all, you can probably fix it. Odds are its just gummed up. You could pull it out and take it to someplace that works on watches.

Or just wash it well with denatured alcohol, being careful not to wash off the face paint.

Then some really light oil applied sparingly to all bearings and the tube the hands ride on should do it.

Thats if it says Quartz like the one in the picture.

If its one of the older ones, there is one more thing to check.
The older ones were windup clocks. They had a set of contacts hooked to the mainspring that powered a solenoid.

When the contacts touched, the solenoid fired pulling them apart and winding the spring about a 1/4 turn.
As the balance wheel allowed the main spring to unwind, eventually the contacts touched again and it all started over again.

If you have one of those, the contacts may be dirty.

I found out how those worked when the balance wheel fell off one in my mother's car as I was driving it through town.
The mainspring unwound as fast as friction of the bearings would let it.
The second hand was invisible, the minute hand was a blur, and the hour hand was running about 30 rpm.

All this accompanied by the machine gun sound of that solenoid hammering away behind the dash.

Scared the Cr*p out of me. I expected to see the sun going down fast. Thought I had driven into some kind of time warp.

I got my old original clock working by spraying electronic cleaner and WD40 inside it and letting it set overnight to allow all the fluid to drain out of it.

Mine works perfectly and does not drain the battery.

Getting the clock to work was extremely important to me, critical to a working oem dash. My clock has the plunger at the 12-o'clock position.
 
Joe you can have it mine works I just one to get a new second hand off another one. I could just find one that doesn't work for that. Hate to take one off a perfectly good one to fix mine.
