I have owned a 1991 Camaro RS V6 for a few years now and when I bought it, the speedometer did not work at all. Well, over the years the whole cluster has been replaced. Now, I'm having some peculiar (at least to me) problems which seem to me, to be a wiring problem of some sort. The speedometer works some of the time, but it will act as if it has a poor connection. Sometimes it only works when I put my foot on the brakes. Also, sometimes when it rains, it seems to affect it. Any info would be greatly appreciated.
