compressor Reman- can't get plug out of High Pressure opening

injun on Sat June 11, 2011 6:41 PM User is offline

Year: 2000
Make: dodge
Model: neon
Engine Size: 2.0
Refrigerant Type: r134a
Country of Origin: United States

Hi- Im in the process of replacing a locked up Compressor in my 2000 Neon. I recieved a reman Compressor via Fedex but it has no high Pressure switch installed.

I took the clip out of the opening that holds a plug where the switch is to be installed but I cannot get this plug out!

I don't want to apply heat until someone tells me that what's necessary....Is there a trick to getting this plug out?

I could probably just leave it in there (assuming it's sealed) and just let the High pressure switch dangle under the hood but I would prefer to install the switch.....

How please????

thanks

I would ask the compressor supplier if they left the plug in when they dipped it in a paint bucket. I've never needed heat to remove a switch port plug.

Thanks...I tried to attach a photo, or a link, but it apparently didn't work. I think the switch is press fit into the opening and so is this plug but there's really nothing to grab onto once I remove the cir-clip.....

I'll try the photo upload again---

Sorry about the photo size.....

Once again....here's the photos....The paint was chipped by me trying to wrestle it out with pliers....

I cannot get this thing to move!

Taking the snap ring out will make things a lot easier.

LOL, I did take out the snap ring as I said in my first post. I have since put it back in......I called it a "clip" but yes it is indeed a snap ring....

Anyway, I got a suggestion on another forum to use compressed air on the return to pop it out....Problem is I'm too tired to try and figure out which post that is on this compressor.....

Is it the one that's attached to the condenser?

Thanks

P.S. I haven't worked on any of this stuff in nearly 30 years so forgive my ignorance. The last time I did an auto a/c job was on a '79 Nova around 1981-ish.....

Hmm, no edit? Anyway I meant PORT in my last post....Which port is the return? The one attached to the Condenser?

Yes, the switch is tee'd into the discharge port the one that goes to the condenser, typically a smaller line.

It's not pressed in metal on metal, but there is an o-ring on it.

I have a new switch and it came with an Oring, the old switch is the other compressor literally self destructed when the compressor locked up.....

I just cant seem to get this damn thing to come out! My intuition tells me some heat will free it but again, I hesitate....

The air didn't work....

Well, that didn't work but looking at the plug under a m-glass I realized that the button in the center is like a nail head in that it's larger than the body it's attached to, but just slightly.

I used a screwdriver on two ends placed under the "head" to pry it out.....

This little snafu cost me a few hours......

Trick, not really-- just put some compressed air in the discharge port and put a rag over the plug first- then apply the air....should just pop right out.

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

The plug has a small groove. Stick a small screwdriver in the groove and pry it out.
