So, I own a 2008 Jeep Compass Sport. I purchased my Compass back in July of 2010. About 2 months ago, I noticed my Compass making weird noises. It was sort of a knocking noise and NOW it's making a weird squeaking noise. I brought it to the dealership that I bought it from, they told me it's the A.C. compressor and idler and tensioner. They quoted me over $1000, now mind you, I have a 4 month old baby I have to take care of. So, I definitely can not afford $1000. I brought it to a different mechanic, he said it's absolutely NOT the A.C. compressor but possibly the idler and tensioner. He also said he thinks it's the Powersteering pump. So, we had him replace the powersteering pump. It's still making all the noises, hasn't gotten better it's actually gotten much worse. Now he says it's the alternator.. IDK what the hell it is and I can't be dishing out all of this money for it not to be the issue. I need some help with this. Is it the alternator, idler and tensioner?
