The 98 Buick Century was cooling bet the compressor sounded like a hammer was keeping time with a fast beat.
I turned off the compressor. Got a good on from pull apart. Flushed the coil and condenser with acetone and denatured alcohol.
using this, its an old sandblaster i never did use until now
After cleaning the evap and condenser I replaces with used hoses and compressor. Thought I did a good job. 2 weals later the used compressor started to tap. Not hammer tap but I new to take it back and get the best I could that'd work.
Here is a picture of the brand new orifice I put in.
New one on the left and it;* full of tiny metal particles. So I did it all over again and put a filter in front of the orifice. There are a couple to choose from
and i didn't take any pictures as i west but here'* one that you can just make out.
I am even ready to replace everything again (except the condenser and evaporator.) if needed.
Here is a picture of me jumping the compressor clutch on.......
I know this is a poor write-up. I lost the xD card that went in my old camera so those are phone pictures and taken after I finished the 2nd time.
The most I have invested is the use compressor, r34a @ 8 a can and the filter for 49.00.
I do NOT believe in letting r34 into the environment. If this is helpful to someone great.
I will say for a long time the vents on the passenger side were much cooler than the drivers side, and i made an incorrect assumption I was having trouble with the blend door. It is a sign you are low on ac coolant which carries the oil throughout the system. Also be careful you don't ruin your test valves by running your ***** down far enough to damage the test ports.
I also think i formatted my pictures too large.
