i have a 2004 montana and the gas gauge,speedometer,and the temp gauge all doesnt work properly what can be the problem
Did you check the fuse(es)?
Could you describe not working properly in a little more detail? Do they not do anything, do they move in unpredictable manners. do the work then not then work again?
I suspect a bad ground, a bad dash voltage regulator or ??? More info needed.
