a whole lot of questions

[chuckthetruck]

I am curious as I have never torn apart a cluster before. I have a battery gauge that runs up to completely full then when i rev the engine it goes back to mid range. Is it possible if one gauge goes bad that they are all tied together? If so the truck over heats (meaning up to 3/4 of gauge) then when I brake it floats back down to just below half. The gas gauge has always been off..haha...any help is appreciated.

I have a squeal at high RPMs that disappears when it shifts....what is it?

Window wiper motor just got replaced...i thought i set them back to the right height to return to but it seems to change every time I turn them on and the intermittent will turn on and perform its task once then they come on and stay on till i turn them off. Not to mention they go faster as I am accelerating!

thanks for listening to my list...haha...I LOVE THIS TRUCK..I am learning a lot by working on him.
