2014 Sierra Condenser / Drier Assembly

[Joe 121]

As part of replacing my Compressor, I ordered a drier assembly.  What I fount was that the GM receiver drier assembly didn't fit into the tube on the condenser.  Turns out the tube on my condenser is 14 1/2 inches long and the drier assembly is 17 1/2 inches long.

 

In 2021, I couldn't find the leak and took it to a shop I had done business with in the past.  They found the condenser was leaking (big surprise).  I told them to go ahead and replace it.  He did and everything was fine.  It would appear he got an aftermarket part that fit, but all he know is he got it from a local parts supplier.

 

When I found a replacement AC Delco condenser online for $170, I ordered it.  The part was advertised as

ACDelco Gold 15-63889 (19383805) Air Conditioning Condenser with Automatic Transmission Oil Cooler

It didn't indicate it came with the drier, But I already had one.

 

It came in a box with an official looking 'AC Delco Professional' label and the condenser had an 18 inch tube to hold the desiccant. I'm all set.

 

This is where I got myself in trouble

When I went to install the drier, I found a plastic plug held in place with a snap ring.  I removed the snap ring but I couldn't pull out the plug.  I finally got it out with help from a slide hammer and found it had 2 green o rings holding it in place.  In the tube was a Desiccant bag.

Here is my problem:  I destroyed the plastic plug by using the slide hammer.  There are no threads in the tube to allow me to install the GM Drier assembly.

 

Does anybody have idea where I can find a drier assembly with just a plastic plug and no threads?  Should I have been concerned when I received a box that had been opened and resealed with official online marketer brand tape?

I just spoke to AC Delco support.  AC Delco Gold is for aftermarket parts, not original equipment.  All she could tell me is that she could find several notes from dealers regarding 'fitment issues' for this part number.  She couldn't tell me what the issues are, for that I would need to speak to a dealer.  She also couldn't give me a part number for the AC Delco Gold Drier assembly

 

I went to the AC Delco website, but, I keep getting 'There has been an unexpected error, please try again later. when I try try shop the GM Parts Store.

I got it all back together and it appears to be working. 

 

On to the next problem.  I have 50 degree air coming from the passenger's side duct and 70 degree air coming from the driver's side duct.   Score one for the dual zones. 

 

I believe the next step is to pull apart the instrument panel to get access to the Air Distributor Case.  At least I don't have to pull out the entire HVAC  module.  I would appreciate any input from anyone familiar with this particular device.

 

Also, can anyone direct me to GM document on expected Hi and Lo side gauge readings?  The internet has plenty of opinions that don't necessary agree with each other.

Joe,

 

Just saw your post and I have the reverse problem AC only cold on passenger and now not AC on either side. I just replaced the driver side blend door actuator. Its like ~$30 and you can replace it without removing the entire dash but it is not a fun task to do. If you follow this video it covers just about everything you need to know about this problem.

Thanks Jacob,  I'm a little behind with my responses.  I ordered the part referenced in this video, just haven't had time to install it.
