Can anyone provide me the instruction and the procedure and how to Replace the Ac compressor on my Z4. Would you be so kind to link any instructions or videos for me? I am usable to search for this topic correctly and some links to the PDF don't seem to work for me. BTW is there a compressor relay in our cars? and where can it be found? BTW see the pic of the part I have removed for the compressor.
2003 Z4 AC Compressor is locked up and sized

Thank you Sir! for the offer I am in the States, however. Just got one from EBAY today. Would you be so kind on how to get started with any installation procedures? BTW is there a compressor relay in our cars? and where can it be found? Would it be under the fuse box or under the hood?
Looks like I may need to remove the hoses from the other ends from the opposite sides of the compressor before removing the compressor.
Will have gas purged by an AC professional before I do any work.

I just did my AC compressor replacement about 3 weeks ago. OEM AC compressor clutch would still kick on but no cold air. Changed the expansion valve (a common problem) and still no cold air. Thought the car was maybe in transport mode but nope!
The AC compressor relay is surprisingly (unlike the other relays) in the engine bay in the fuse box. It's this little green box on the diagram!
Edit: I'm not sure why you're asking about the AC relay since it's highly unlikely to be the culprit -- they're thankfully quite reliable unlike the relay for the wipers. Either way it's good to have more info

Also, yes - remove the hoses before the compressor but be VERY careful to not strip the allen screws that hold the hoses to the compressor--they're super soft compared to other bolts I've dealt with. The electrical plug at the top of the compressor can also be finicky to unplug if it's very dirty down there.
Oh and maybe remove the hose where it connects to the radiator because you will need to fish out the AC compressor from underneath the car. Don't forget about filling the new AC compressor with PAG oil (some already have it pre-filled thankfully).
Good luck!

Motionblurr WOW you guys are the greatest on this site. Thank you so much you for the heads-up sounds like you know your stuff. Regarding the Relay like to as much as possible about what I am getting into before. Your info is amazing guy! We reach over 90 degrees out here so will be putting the AC on the bimmer at a later date. Got other issue with my CLK today with the wheel hub replacement. Sweating my nuts and bolts off
