2004 montana Faulty gauges

[duane999]

I have a 2004 Montana and all the gauges are working eratically. Sometimes they will work and most of the time not. They seem to work better when the temperature outside is hot. On a cool day or morning they go heywire. Any ideas where I would even begin to look. Do I have a bad ground wire somewhere?

Thanks,

Duane

I found this add on craigslist one day and that is the first I've heard of it I don't know how they fix them or what fails . Keep us posted

The stepper motors go bad. They replace them. This is a known GM problem.
