1996 Chevy Blazer altinator

if drive belt around alternator is OK then the alt. may need rebuilt soon.

ok i think i might try and replace the belt and if that dont stop then i will go out and buy a new alt. and i have a few more questions to ask. on my blazer my rear wiper on my truck just stoped working the moter is still working but when i turn it on it dose not like to move the wiper blade it seems to be stuck but when i turn it on and go move it it will work could that mean i need a new belt for that or a whole new motor

gear may be stripped or the bolt may be loose. take the cap off at the end of the blade and should have a bolt there, try tightening it up.

ok i will try that when i get back home and see if that stops the problem and that the blade will work lik i said it will move when i go and tap it when its on so im thinking it could just be that cap and how much do you think a new coolent line would cost if i would bring the truck in i have a few things wrong with the car distrubitor cap is bad and the gas gauge dont work replaced the pump and when i did that i filled it up and it went to full and never came down it will move at times when car is off but when its on gose rite back to full
