HOWDY, I AM COMPLETELY NEW TO THIS AC WORK , MY COMPRESSOR FROZE UP SO I TOOK IT OUT AND DISASSEMBLED IT, ONLY TO PUT IT BACK TOGETHER AGAIN, I ADDED OIL AND GOT THE CLUTCH TURNING PRETTY FREELY BY HAND NOW, IS THAT A GOOD SIGN THAT IT IS GONNA WORK NOW, IS THERE ANYWAY I CAN TEST IT TO BE URE? ALSO, MY EVAPORATOR HAS A FEW "FINS" WHICH SEEMED TO HAVE BEEN PERHAPS MELTED OR DAMAGED IN SOME WAY, DOES HAT MEAN I HAVE TO REPLACE IT, I AM TRYING TO GET MY AC UP AND RUNNING FOR AS LITTLE AN INVESTMENT AS POSSIBLE SO I DON'T WANT TO REPLACE THINGS UNLESS I HAVE TO. THANKS!
I would NEVER re-use a compressor that 'froze up' since it will likely blow up later on causing the need to replace everything all over again. Get a rebuilt one. The evap may be clogged with dust and dirt (over 15 yrs). I replaced my evap in a 22 yr old car cause it was so clogged with dirt, dust and mold that it was beyond hope.
Not too many people can actually see their evaporator fins-- so maybe you are talking about the "evaporator" in front of radiator??? which is known as the condenser.... a few bent fins there is no big deal- as long as there are no leaks....
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
i removed the evaporator from underneath the dash of my truck so it is definitely the evaporator. is this damage compromising.?notebook
Absolutely you need another compressor. If it seized up there's going to be considerable internal damage. After the parts are torn up it may turn again but they don't seal to each other and it won't compress very well.
On the evaporator as well as condenser, no need to worry about a few bent fins as long as the coil doesn't leak. But because of the compressor failure, replacing your condenser would be a good idea. When a compressor grinds itself up inside, most of the debris lands in the condenser. These trucks have a serpentine type condenser which has baffles in the interior passages, making it very hard to clean out.
Also always replace the receiver-drier with a NEW one as part of any major repairs. It's an expendable part like an oil filter.
Did you find any metal debris in the expansion valve screen when you took the evaporator case apart?
i havent checked the screen , thanks for your help
hey one more thing where can i find the screen?
