Need Help: AC Compressor for 99 Chevy Silverado

I’m currently having issues with the air conditioning system in my 1999 Chevrolet Silverado, and I suspect it might be the AC compressor that needs to be replaced. Does anyone have recommendations on which compressor works best for this model?

Here’s what I’ve encountered so far:

  • Symptoms: The AC isn’t cooling as it should and I’ve noticed some strange noises coming from under the hood when I turn it on.
  • Previous Repairs: I had the refrigerant checked and refilled, but that didn’t seem to help.
  • Budget Concerns: I’d like to keep the costs down if possible, so any advice on affordable and reliable options would be appreciated.

Questions I have:

  1. Brand Recommendations: Are there certain brands that are known to be more reliable for the 99 Silverado?
  2. Installation Tips: Is it something I can do myself, or would you recommend hiring a professional? If DIY, are there any guides or videos that you found helpful?
  3. Signs of a Bad Compressor: Besides the noises and lack of cooling, are there other indicators I should be looking out for?

I’ve done some research, but there’s a lot of conflicting information out there. I’d really appreciate any firsthand experiences or advice you all might have on this. Looking forward to your replies!

Hey there! Replacing the AC compressor on a '99 Chevy Silverado can definitely be challenging, but with the right tools and steps, it’s manageable. You’ll need a wrench set, a socket set, and some refrigerant if you’re going to recharge it after. Don’t forget safety glasses!

Absolutely! Also, make sure to use a vacuum pump to remove any moisture from the system before you recharge. It’s crucial for the longevity of your new compressor.

Don’t forget to wear gloves while working! You don’t want to mess with any sharp edges or contaminants. Plus, it keeps your hands clean from the greasy parts.

I found removing the belt is usually the trickiest part. It can be a fight, so definitely line up your tools ahead of time. Anyone have tips for that?

Yeah, using a tensioner tool can help a lot. Just be patient, and it will eventually loosen up! Have you done AC work before?

Once you have the old compressor out, check the hoses for damage. Sometimes the real problem is with the hoses and not the compressor itself! It can save you a headache later.

Great point! I learned that the hard way. Ended up replacing the compressor only to realize the hose was leaking. It’s worth the extra inspection.

As for tips, having a good magnetic tray for screws and bolts is a lifesaver. They tend to vanish in those tight spaces otherwise!

And make sure you disconnect the battery before starting the work! Safety first! Imagine accidentally shorting something while under the hood.

Absolutely! And keeping a working phone handy in case you need to call for help is a smart move too. You never know!

If you run into issues with the electrical connections, watch out! It can be a bit of a puzzle figuring out where everything goes back.

13

For real! I’d suggest snapping a picture of the setup before disconnecting anything. Makes it easier when you’re putting it all back together.

14

Just a heads up, if you have to add oil to the new compressor, be careful not to overfill it. Too much can lead to issues down the road!

Quick tip: Don’t forget to check your fuses! Sometimes if the AC isn’t working, it can simply be a blown fuse instead of a compressor issue.

That happened to me once. I was totally ready to replace the compressor, but a tiny fuse did the trick! Double-checking these small things can save time.

If anyone is worried about costs, you can often find good deals online for aftermarket compressors. Just make sure to read reviews before purchasing!

Exactly! I had a squealing noise before mine gave out completely. It was a mess! Anyone know if the rebuild kits are worth it?

Mine leaked refrigerant and caused the system to fail. Check the connections and ensure they’re tight or else you might face major leaks!
