Some history:

Since the first of these clocks (U35 Clock, quartz ) was offered in 1982 and the last in 1985, I suggest that most are non-working. The clock, for example, in my 85 IROC wasn't functioning when I took possession of the car around 1998. At that time, before sending the clock to a repair facility, I decided there was nothing to lose, so I blew the works out with compressed air and shot them with WD-40. Before you object to the latter, note that that fix lasted from 1998 to 2020. If you have better suggestions, please note them below.

Tools:

7mm and 10mm sockets. Philips screw driver. Extensions as needed.

Upper console:

1. With the console lid open, remove the two storage-area fasteners with a 10mm socket.

2. Remove the two Philips screws at the front lip of the storage area.

3. Engage the parking brake to allow the upper console to be raised.

4. Lift the upper console a few inches and support it. I used a long extension.

Removing the clock:

1. Unscrew the three 7mm fasteners that secure the clock to the upper console. I strongly suggest covering the area below so that when a fastener or tool is dropped it won't be lost.

2. Slide the clock toward the shifter to free the clock's long crown (used to set the time). Then jockey the clock through the space between the upper and lower consoles. With the clock free, removing the harness is much easier.

Removing the clock from its white plastic case:

1. Unscrew the three small Philips fasteners from around the lens.

2. Lift off the lens and metal bezel.

3. To expose the clock's works lift the clock out of its case, being mindful not to compromise the two wires that connect the case to the clock.

Cleaning:

1. Blow the works out with compressed air.

2. Squirt a bit of quick-dry, plastic-friendly electronics cleaner directly on the works (I'd avoid any other parts) and use the crown to manipulate the hands. Use a cotton swab delicately if necessary. Repeat if required. I didn't follow this step in 1998.

3. Shoot the works sparingly with WD-40 or PB Blaster and use the crown to manipulate the hands. Clean up any excess.

Finishing:

Before restoring the clock to the console, I plugged it in for a few hours to see that all was well. No issues several days later.

Considerations:

If the lens is scarred, as it probably is, now is the time to consider a polishing of some sort. (I used toothpaste this time as I went all out in 1998 with wet sanding and so on.) If the bulb(s) are burned out, replace. The hands are plastic, of course, and with age susceptible to breaking. Personally I wouldn't touch them.

The console clock is one of the coolest options IMO.Ive installed them in both my 86 and 89 irocs.I have also acquired a pretty good collection of them throughout the years and in my experience they pretty much always work although some take a bit of coaxing.Your lens looks very clear.Whats the best way to polish these?

Years ago I used the wet sanding method with various grades of paper, a polish and a buffing wheel. Nowadays, a headlight restoration kit might be the ticket.
