Lost a/c checked fuse and was blown. compressor kicked in no cool air, next town i stopped made a noise after restart. noise went away, only to come back louder and all the time is it a critical issue or a convenience of a/c
A high-pitched squeal could indicate a blown A/C clutch or a seizing compressor. Also, check adequate coolant pressure/amount in the system. The a/c gagues are inexpensive and available at auto parts stores and some Wal-Marts. I assume the blown fuse was for the compressor switch, this could be caused by either a temporarily seized compressor (ie: clutch) or inadequate coolant/lubricant in the system.

It sounds to me that your belt or tensioner is worn, if the noise goes away when the ac is off then it is just the belt slipping, it takes a lot of power to run the compressor and if the belt is worn it most likely slipping on the pully when you engage the clutch.
---------Have you replace your airfilters? might be dirty so clogging-up no air is coming in to the ----------------------intake which sometimes causing noise and you can hear that fr your vent. Also check your----------------your AC fuses maybe blown-out. Also one one that cause noise is the fan that spins-------------------------faster than its normal when AC is on. Generates more air to cool down radiators. Hope-----------------------that theres nothing wrong with your engine so better check an oil leak and your engine oil
The seal on the AC compressor has probably failed and allowed all the refrigerant and lubricant to be lost. This allows the bearing to run dry and now it is failing and making noise.
1. You could have the AC repaired, the compressor repaired or replaced and the system refilled.
2. You could have a mechanic disconnect the system and possibly remove the compressor (only if this model does not use a belt that relies on the compressor being in place).
3. It is probably way too late to try to refill the AC system with R134a refrigerant as it would just run out past the failed seals.
If anyone has an AC unit that just recently stopped making cold air they should attempt to recharge the unit (if it uses R134a - check your manual or underhood stickers). I just did and saved my compressor and AC unit from further damage.
the compressor is mounted down low in the left front behind the left headlight. it is powered by a large fuse in the under hood right side fuse panel. if the fuse is good.flip off the trunk suspension switch,jack up the rear wheels and check to see if the sencing arm that attaches to the rear end has fallen off it's pivot. if it is unattached it will drop both rear air bag pressures quickly.
good luck chris
Sounds like the compressor isnt getting power nor told to do so.
My first step to try for power is to go to the engine bay, Go to the fuse box above the engine and swap the Horn relay for the one in air suspension and try using the horn. If the horn doesnt work theres your problem!
Next step if above fails. Is to check for any blown fuses and replace as needed then retry.
The air suspension also has a height sensor on it, If that has failed the car wouldnt work out where it was and wouldnt adjust. also there is a Air Suspension/Evo Steering Module which controls the system but if there was a problem with this i belive you would also loose power steering.
look for the a/c relay located (likely) in the fuse panel in the engine compartment near the battery. if it's not there let me know and i'll find out which relay it is. incidentally there may be fuses blown as well and replacing them may bring back your dash computer as well... i believe there are also fuses/relays located in the trunk as well on BMW's.
It sounds to me like your compressor got killed. What probably happened is that the airbag got a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag killed the compressor. I would recommend going to strutmasters.com and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car.
