 Subject: It just never stops...

Message:
Just when I think I have fixed all my Dak problems, and it is running fine, BOOM. Another problem that I didn't cause. The AC died. I did some troubleshooting and determined I had a bad leak.
The shop thinks the leak can be fixed with seals, IF the tube on the condenser is not cracked. But they say I should replace the accumulator/dryer too.
Cost of $400-500 total. Is that reasonable? The shop has a good reputation, that's why I went there.
But I have no experience with AC.
This is the first AC problem I have had with my 1994 in 9-10 years.

Fix that yourself. I have replaced almost all of my a/c components. The only thing factory is the condensor. All new parts except a compressor from a salvage yard.
The condensor is a little harder to get to since it sits next to radiator. the accumulator is very easy to get to, sits next to firewall on passenger side and just requires a special tool to remove the lines. I picked mine up from autozone. I got the plastic ones for $10. I at first tried the metal kind, but the plastic is much better in my opinion.
The shop should have left the system evacuated so you don't have to worry about that. That's can be a costly part.
If you dont feel up to the task, you can replace the accumulator yourself (be sure to use new o-rings). Have them replace the accumulator (call back and ask for price for just that). This way they can vac out the air and put in new refridgerant. When I did mine, the shop I use only charged me $24 to vac out the air. I put in the r-134a myself. Most shops around here won't just do the vac for whatever reason (maybe they want money?) and charge in the neighborhood of $90 to vac out air, test and put in refridgerant. When I called they were very surprised I was going to replace parts myself and would not flex on the cost/service.
replacing the accumulator is very simple. I can provide some pictures and instructions if you need. Also, is your 94 r134a? if not, now's a good time to convert.

Hey Dan,
I looked on partsamerica.com
I think they had all I need.
They had 2 pages of inline filters. What are they and where do they go? Do we have those??
I had to get one of those hose tools for the fuel line. Don't think it is the same size though.
So, if it was evacuated, all I have to do is install the parts and add R134a, correct?
Are there any "sealers" (other than orings) needed for the connections in the hoses?
Thanks

You mention fuel line tool, are you referring to the scissors type metal tool? The a/c components use quick disconnect. The tool slides into the component to release the snap, then you slide the hoses apart.
Anytime you have a leak or open the AC system to replace parts you can't just fill it with refridgerant after you have replaced the parts/fixed the leak. You need to evac it to remove all of the air. Then add the refridgerant.
I am only aware of o-rings on the fittings.
haynes has good book that explains in detail the heating/ac systems and theory. I picked this one up when my a/c went out to better educate myself.
The plastic disconnect set I am thinking of comes with 4 sizes. Advace/autozone have them. They are plastic and round. Each a differnet color. My 95 used 2 of them. the in/out hoses on the accumulator are differnet sizes. The Accumulator is the component that feeds into the evaporator core. The connections will be a few inches from the firewall.
Most of the cost in replacing a/c components (besides the evap core) comes from the shop evacuating the system (they have to properly dispose of the refridgerant via EPA guidelines/laws) and in adding refridgerant (You can get it at wal-mart for like $6-7 can. You will need 2 cans.
You gonna be around this weekend? Send me an email, I can hook you up. Wife is off work so tonight is out, we have plans.
