rgent Help Needed, Please-A/C Clutch
Just found out that my A/C clutch needs to be replaced. I got price of 280.00 to install a re-mfg one, but I don't have the money or the time. I need to finish moving tmrw.
Can I by-pass the A/C by installing a smaller serpintine belt. The diagram for the belt installation without A/C is right under the hood. If I can do this I can get a belt tonight. Also, as winter is coming, I can save for a new one with a warranty.
If I can not by-pass the system, is replacing a clutch & hub a DIY project?
Greatly appreciate any input....

On my 99 Blazer there's an electrical plug that connects right behind the clutch. Disconnect it, and the clutch doesn't engage. Hope that helps.

Assume the clutch bearing is squalling now as it chews up your compressor snout.
No you cant, unless they changed the compressor location from 99 to 2003 {Gee.. how did I know you have an 03!}. You either need to fix it or get a delete pulley. If you can pull your compressor to the side and tie it off that's the thing to do.

Amazing... people ignore the bad bearing noise until it's too late.

Sidenote: Bravadiva's clutch bearing just started singing. I immed ordered the bearing and tools, total 55 bucks on line. Thing is you have to have a hydraulic press to remove and install the bearing.
My brother does.
.. now to just get energized enough to do it. Hopefully I wont wait till I'm in the same pickle.

Not the point. Unless your year and model are shown in sig or namebar, identify what you're referring to so we dont have to guess or search your previous posts like I did.

Regarding the clutch problem. I am going to order the parts needed, but I was wondering,since the noise on comes when the clutch engages, and I really don't need the A/C for a few months, can I just dis-connect the electric connection as pointed out in the other reply above.? I only want to do this until the parts come in. I really need to finish moving, and I have most of my personal items inside the blazer. Not a whole lot of things for a guy that has been around this life for over 65 years. Kind of depressing really. Oh well, that's for a different forum.
Please let me know about un-hooking the connection.
Thanks again

Goes to show you.. Never ASSuME.}
Yes. As Armstrong001 suggested that's worth a try. If unhooking the connector to compressor stops the noise, then do it. Good idea even if it's the bearing that causes the noise.
You can also pull the connector at the accumulator to stop compressor from running.
Anytime you get more noise than usual when compressor runs, do this immed. that means pull over and do it now. You may save yourself hundreds of dollars.
Pulling the connector at the accum bottle is recommended because it's easier and cleaner. Wont get hands as dirty.
Now for the bad news. Are you sure the noise is from the clutch? That would mean it's slipping. and grinding itself up. That may be the clutch itself or it may mean the compressor is going south.
Yeah... I know. you needed that, didnt you. Sorry.

I had it in the hsop the other day and they pointed it out to me that it was bad. When I spin it by hand you can hear it rubbing/grinding. It's also, kind of hard to spin by hand. It gets lound when it kicks in, about every fifteen seconds.
Regarding the connection at the accumulator, I can only see one such connection so I am assuming there is only one. I do not want to have freon spraying all over the place.
Once again, thanks for your help...
Edit Update: I meant to say that it stops spinning after about 15 minutes, then makes the noise, when it is spinning it does not make the noise. Sorry to confuse you..I already have enough confusion for both of us....

So.. lets clear this up. The pulley rides on a bearing that is critical whether or not the clutch is engaged. The inner race fits on the compressor housing snout, not the shaft of the comp.
If it only makes the noise when the compressor clutch is not engaged, IOW front of clutch not turning, then you either have the problem I originally thought you did.. bearing .. or the clutch is deformed.
- Turn the clutch by hand, without pressing it in, and see if you feel it rubbing. If that's the case, dont bother disconnect, wont matter. But if it's the bearing replace brearing or assy soon as possible. You could also see if you can move the compressor aside - off the engine and secure it- and install a delete pulley.
If it only makes the noise when the front part of clutch is spinning then the clutch is either slipping or the compressor is ready to grenade. Either way disconnect is imperative
