Replace the drier if you suspect any moisture in the system as the drier absorbs moisture & can cause the system to not function properly. You will have to have the drier installed  the system evacuated by a professional , checked for leaks & system charged. Then you should be good to go.

I'll pick up a drier and filter (Not sure where its installed) and drop it off at the shop to be redone, if nothing else I be closer to a all new system  Grin . I'll keep you informed if it works, glad the people out in the shop refill and vacuum the system for free, well not free I am  sure it will cost me in the long run.

Figured out something was wrong with the new compressor, found metal shaving in the lines. Time for new filter and system flush and a new compressor again. The positive side is all new O-rings  Smiley, I'm still money ahead, then knowledge I've gained and extra shop time "price-less".

Ron that really sucks.  Sorry to hear it but from your description of the problem I was afraid it might be the compressor. Shocked  Glad you are "enjoying" the "PRICE-LESS" part of this repair. LOL Grin  Good luck.

we'all learning from this RON. maybe I won't salvage the compressor I have and go ahead and get a new one when I do mine. Maybe I can get a core charge out of it at least.

Hang in there,
Charlie

Ron, saw in your other post you found paperwork where PO coverted to R134.  Are you still using R134?  My statement of the system using 3 pounds of freon was assuming it was R12.  I seem to remember something about coverted systems using between 10% to 15% less R134 than R12. Undecided Shocked

Charlie,
Recommend flushing the system, replace orifis tube (On the 77 its located on the small tub that has the thermostat on it, I replaced mine after the flush but that is where I found the metal shavings), replace all the seals (there really isn't as many as I thought), Vacuum system (Did mine for 15 minutes), let it stand for 15 minutes to ensure there are no leaks, Add freon 3lbs if its R12 and 20% less if its R134. If you replace pump don't forget to add the compressor oil, I changed the drier just to be on the safe side. Check to ensure the air is cold and enjoy.
Dale,
You have to find the positive if things aren't going right. Learned a lot from this repair. The parts store thinks the pump was bad from the start since the pump I exchanged was only leaking and no damage is evident from the inside. They say they will replace the pump free of charge but I have to wait for one to get ordered in, should be here in a couple of days. so really the only thing I am out is the orifis tub, flush since I used the oil and freon from work, and time. I figure this time I will add 2 1/2 to 2 3/4 pounds of freon and work up from there.

Ron

Ron, at least it's good they are going to stand behind the compressor.

Thanks Ron. I'm converting mine to the late C3 so I don't have to use the VIR and am getting a parallel condensor and C4 blower so I'll be expecting good results out of mine. Ya know, I have one parts house that I always go to and am in there quite a bit and they always give me the benifit of the doubt if there's ever a discrepancy. sounds like you got a good one too and what they did for you would seal the deal for me.

Charlie,
I've done business with the same parts store for over 24 years. The only time I go somewhere else is when they are closed and can't wait for parts, normally they have whatever I need in stock.

Well, new pump came in today. Flushed out the system with two quarts of cleaner, replaced the orifice filter, filled the pump with oil, replaced drier again, hooked every back up and I have air conditioning. Was real nice driving home. 
One issue down two more to fix: 1) window washer 2) cruise control, well there is the rear window defroster but I am not going to worry about that since I will probably never use it.

The blower motor on my 1971 appears to have failed. Blows the fuse whenever the fan is turned on. Would appreciate any guidance on how to replace the motor.

It depends on if you have a SB or a BB with or with out air. A SB you can get it out from the top from the engine compartment. A BB from the side is easier. I did it from the top on both.
