isham42 Posted April 27, 2008 Report Share Posted April 27, 2008 i have 1998 eldorado, 4.6L northstar ...... last year i was having a problem keeping freon in the car.....i discovered a fitting connection that was left loose. so i tightned it up, and that stopped the leak. this car has had motor replaced last year. when i tried to add freon i couldn't get the compressor to stay on for a minute or two and would not pull down freon. so a mechanic friend of mine told me to boil some water, put it in a pan, take it outside and while the freon was attached to the car, put the can into the boiling water and the freon would be forced into the car, after i cleared the codes......this worked. then i started the car and ran it to operating temp and checked to see if system full. Now the system is FULL of freon but the compressor still will not engage. so i replaced; compressor relay, compressor fuse, high and low side presser switch, still will not engage. still sets code for low refrigerate. that is why i thought the orifice tube filter might be clogged up, or that the low side temp sensor might be bad. i am really starting to see red with this car........i am gaining a undo respect for computer controlled heating and cooling. i long for the simple!! on and off like other cars are...........anyway if anyone has any great ideas PLEASE let me know....oh and today i tried jumping the low temp sensor i read in someone elses post and that didn't work either....the car would't even let me turn the ac on. john Link to comment Share on other sites More sharing options...
