About 2 weeks ago my car started to sound like it had an extra electric motor squelling under the hood. What I have narrowed it down to is the AC motor or AC tensioner by opening the hood and just listening.
Would this be the correct diagnosis steps:
1. Remove the tensioner, check if the bearing is sticking or not spinning freely.
2. Is it safe to spin the AC motor with out the belt on? If so spin it and see if it is sticking or grinding. (does anyone know how much tension i should expect from the motor?)
if it's item 1 that is a simple fix
if it's item 2, does anyone know if replacing the AC motor is a PITA? My concern is the Freon (SP?) lines that are connected to it.
I have 99k on the car, it's on 04. I don't think any of my mods would affect this part of the car.
I have hte 04 service manual, but weirdly i can't find much about the AC motor in the book.
