Purchased the car changed compressor worked good leaked out weeks later so
I changed
AC Evaporator
Accumulator
Orifice Tube
Added two 12 ounces of r134a cans
Compressor working as it should what can it be? Only thing I havent changed is the condenser don't think thats the issue since it was working before?
Purchased a vacuum but believe it does not work keeps stopping randomly
Scotty usually answers questions only once and doesn't revisit them.(Other members will assist you) Here's how to post photos: https://carkiller.com/scottykilmer/notice/read-this-first/#post-183035how can I upload a picture?
Starting from the beginning, why did you replace the compressor? Had it failed internally? If so, you needed to also replace the condenser, drier, and expansion valve or orifice tube. Then the rest of the AC components need to be flushed out with a suitable compound. Otherwise there would be debris left in the system that would damage the replacement compressor. (If the compressor was replaced due to an external issue like bad clutch then this doesn't apply.)
The early 1990s were transition years when R12 was being phased out and R134a was introduced. If this car originally came with R12 had it already been converted to R134a, or were you performing the conversion?
Of course when drawing down the AC system the vacuum pump should not be starting and stopping, it should run continuously and as Scotty says the system needs to be vacuumed for at least 45 minutes. If your pump is not running continuously it is defective or perhaps does not have the right level of the correct oil in it. Here is an overview of the vacuuming process:

If you are not familiar with working on AC systems it would probably be better to have an HVAC technician do the work. It is very easy to make things worse or even injure yourself. (Always wear eye protection when working on AC systems.)
@chucktobias compressor was not locked but was leaking from the clutch area that's the reason I replaced it with a whole new one as for vacuum I believe its bad because even with nothing connected it to it it does the samething im no pro but I didn't my research before touching it followed a bunch of videos I noticed I have the evaporator cold once lines pass the Orifice Tube that's when lines r hot so i believe issue is jst air in system im speaking with amazon abt replacing vacuum
@reyesjose Assuming you do not have a micron gauge be sure to pull at least 30" of vacuum on both high and low sides of the system (open gauge set valves) for at least 45 minutes. Maybe longer since you've had air in there a while. Then make sure the system holds vacuum with the vacuum pump turned off and disengaged (close gauge set valves).
Well of course you have to vacuum. It's just about at least 45 minutes before you fill it up because if you have air in the system it will do exactly that. I would start there since it worked before but just was leaking out. I would also put a little leak Diane to see if it's leaking anywhere still
If vacuum keeps stopping/starting it means what? I even left the vacuum run without connected and it still stops/starts does that mean vacuum is bad?
@scottykilmer how can I upload a picture? I want to show u the spots where lines r cold to touch n rest r hot if I remember correctly all lines were cold except the high pressure line
