So I juss got my 95 db8 few months ago. Everything works and all stock. 3 days into ownership the AC compressor seized. Bought a new (used) one from an HT member with less than 100k miles on it.

Had the AC professionally evac'd about 3 weeks ago and replaced the compressor the following day. Juss had the system charged 2 days ago and its working.

So it does in fact blow cold air, but sitting at a stop light it feels it could be colder! It's only 94 degrees outside.

So is there something I can replace that will make this colder?

 

Is the ac condenser fan coming on?

 

Did you also replace the receiver/dryer and expansion valve? Add oil back to the system?

 

That I will have to check.

I have not replaced anything other than the compressor. I was hoping that since the one the car came with seized, simply replacing it would be all I needed to do…*looks like I have to invest more money into it unfortunately.

I did however find this helpful thread on HT: Summer A/C Guide, How it Works, and When it Doesn't

Based on what that thread says and what you mentioned, looks like the receiver/dryer needs to be replaced OR is that something I can take apart and clean? As far as add oil back to the system, I'm not sure… can you elaborate on that?

 

Make sure your recycling the air not trying to cool outside air.

 

Always! Trips me out that people don't realize that makes the cabin colder

 

Anytime a compressor is replaced you should replace the filter/dryer, if the compressor seizes up you must replace the filter, [it is not cleanable] ad we would also replace the expansion valve.

When a compressor seizes it means bad stuff has happened inside the compressor and that means "chunks", [particles] of metal are pumped out of the compressor and into the rest of the system, most will be trapped in the filter but some can get past.

The proper fix is to replace the compressor, filter/dryer and in most cases the expansion valve, once old parts are removed the rest of the system should be flushed with A/C flush to clean it out, a proper oil charge should be split between the compressor and filter, new O rings used when installing the new parts, a nitrogen pressure test is also a good idea, but not mandatory, a min. of 1hr on a vacuum pump before recharge. 94

 

Valuable information! Thank you. Do I need to have the AC System evac'd again in order to replace the dryer?

 

you need to replace the dryer and possibly expansion valve, put everything back together, then have the system evacuated, you wasted money having a vacuum pulled, then opening the system to replace the compressor in the first place once you opened it back up to replace the compressor, the vacccume pulled was gone

 

OP means recovered, and yes Declectic it will need to be recovered.

Recover = remove refrigerant in the system.
Evacuate = remove air/moisture from system, put under vacuum
Recharge, [evacuate and recharge] = inject proper amount of refrigerant into system.

Just to clear up the terms ^^^ used in A/C service. 94

 

that is good information that i did not know and yes that is what I meant.
