A/C Compressor Seized - DIY Repair Summary

Much to my surprise my compressor seized up with only 56K miles on a 2014 Silverado LT standard cab w/4x4.    Went straight to web and I was also surprised to see that this is not an uncommon occurrence on these trucks around this age.  Anyway, after a few options considered I decided to repair this myself, mainly because I didn't want to pay the high price.  I'm no stranger to wrenching and I was up for the challenge.    

 

Parts:::  

4Seasons Compressor (new)   198381

4Seasons Condenser   40794

4Seasons Expansion Valve     39460

4Seasons O-Ring Kit   26824

PAG-46 oil

A/C Flush Kit w/ flushing liquid

 

You will need to get a new A/C belt, might as well get all three belts to replace.  The inner two belts are stretch belts so you will need a zip tie to get them on, the A/C belt goes from the rear of the harmonic balancer, not the front, watch a youtube...

 

I flushed the evaporator and all hoses with the flush kit, there was lots of oil in the evaporator, took a while before the exit looked clear.

 

I replaced all O-rings..

 

I had an issue with new transmission oil line connectors that came on the new condenser.  I think the inner diameter of the new connector was bigger than the original because transmission oil leaked from the connector around the line going in (the O-rings looked good).  I had to re-use the original connectors to get the leaking to stop.  Make sure to put new O-rings into the original connectors before installing, they came with the O-ring kit.  

 

The new compressor was pre-loaded with 3 oz. of PAG-46 oil so I added 3 oz. to the condenser to get the total spec capacity of oil called for in the system.

    

Pulled vacuum for an hour and then charged the system with two cans of R-134a (24 oz total).  Checked out good with the pressure gauges.  

 

Cold air again!

Same thing happened to my 2014 GMC Sierra and my wife’s 2015 Suburban at similar mileages. Not far outside warranty. GM quality at its finest!!!

 

These vehicles begin to fall apart at 75k. I think I’ve had it with GM.

Engineered failure at it's finest.

 

Fortunately for me, I had an extended warranty till 100k miles. My condenser failed and later my radiator failed. Both replaced under extended warranty and after the factory warranty had been long gone.

More of GM's latest junk. To think I have always been a GM guy. Never again.  14 Sierra,  just turned 50,000 miles.  2 expensive failures that were out of warranty already. Now going on the 3rd.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
