My clock stopped working yesterday.

I checked fuse no 9 and it looks good.

Any ideas as to how I can get it fixed ?

Continuity check with DMM is the definitive check of fuses.
The holders may have some corrosion buildup.

Does it not work all the time on only when the key is out?

If you give up, try Palo Alto Speedometer on Emerson just south of University.

Clock stops when very cold.

Thanks!

I got a feeling it may be the capacitors. Another electronic job Sixto!

I will clean fuse receptacle 9 and see if it solves the problem.

Mine works for a bit, then stops. I set the time, and it works for a while, then stops again. Anyone know about that? Its on the 92 btw.

I prefer using a 12V lamp when doing critical checks on fuses. A DVM will work if there is a small leakage current but a lamp will only light up if the fuse is good.
Its also common to get corrosion on the fuse ends where they touch the holders, I believe the blue fuses are the ones that are now available with copper colored metal strips, this is preferable over the aluminum strips that were common before. It a dissimilar metals thing that makes them corrode.

As for the clocks, it sounds like shorted caps. That also burns out a small resistor on the back of the clock, I've had to replace that also. Its a job that requires some skill and a small soldering iron but you can save a bundle if you DIY. The hassle you might have is getting the instrument cluster out far enough to disconnect the speedo cable, the proper way is to loosen it at the transmission for some slack, don't pull on it or you may damage the cable
