View Full Version : pulley on my AC is seized
Jul 2nd, 2012, 01:14 PM
The pulley on my compressor (ford windstar 2002) is seized and the belt simply slides over it.
Is this something that can be repaired or does the whole unit needs to be replaced.
I imagine thats a expensive thing to do. I really dont care if the AC doesnt work. Can someone suggest asolution.

you have at least 2 problems on that compressor.
1. the clutch bearing is locked up
2. the compressor itself is locked
or the clutch piled up so violently that it locked the pulley to the housing or something.
if no need for AC, you could get a shop to pull the clutch and replace the bearing and it will turn again (they might have to take out piled up clutch, but that would be easy)
Whether it can be done in place or compressor needs to come out, depends on the vehicle - some have room to pull the clutch, most don't
If your refrigerant is gone, they could just sawzall the lines and make compressor re and re quicker.
was there a non a/c version of that vehicle? probably not, but if so, there might be a belt that would go in there without the a/c comp.... doubt ti htough... a lot of stars would have to line up - like all the other pulleys and routing the same... not likely

replace the belt with a shorter one, don't put the new one on the a/c compressor. Its going to be a pain to find, but a good auto parts store will have the belt

If the pulley is seized then the belt would be burning up sliding over it.
I suspect the clutch is not engaging and the pulley is just not turning the compressor.

what ive been told is if the clutch fails and sticks or even compressor there main shaft inbetween has a breaking point where it will cut off the compressor allowing the clutch to rotate. this prevents the compressor from grenading if it was solid. and or belt from frying and leaving u stranded if its a 1 belt system.
