The A/C comp will not come on neither will the cooling fans. I pulled a vacumn & it took half a can quit. I tried to pull codes pressed the off / warmer nothing appeared. No power to the cooling fans or the 2 /40 amp fuses ? Where to next i don't have a wiring schematic. Not familiar with Caddy i work on 70 older.

=========================
you NEED to be able to pull and clear the codes -

IF there is a "LOW FREON" code stored - the compressor is disabled
and will NOT engage until the code is cleared -

 

[sefiro]

Yes, clear codes. Did you get a segment check when entering diagnostics?

Your initial fill after vacuum should have been a full can. Did you let it sit for a while under vacuum and did it hold?

 

[SnakeBitN]

I did let it sit for awhile before adding the freon and it held a vacumn.I tried to pull the codes by holding down the off & warmer temp button Nothing ! I disconnected the battery let it sit for an hour to clear codes. The compressor came on took a little freon then pegged out the Low guage. I cut everything off parked the car,closed shop with my tail tucked.

 

[sefiro]

The low side pegged? Was the hi side at same psi reading? If so, then orifice is blown

 

[SnakeBitN]

No they weren't the same reading. I replaced the orifice tube earlier and it was full of debris (metallic). Iam going on and put a new comp,dryer,and all flush out as much as I can.

be sure to add an in-line filter -

Replaced A/C comp, dryer , orifice tube pulled vacumn for hour. No leaks. Added 2 cans still no cooling fans coming on. Low side kept going to the high side of guage when cycling on & off. My high side guage not working worn out hose going to get a new. My concern why are the fans not coming bad fans or something else.

 

[Ranger]

You need to replace the condenser as well. Being a lateral vs serpentine type, it is difficult to flush. Any debris left will take out the new compressor.

 

[SnakeBitN]

Any thoughts on the cooling fans I replace the right one only one my A/C Delco store had. Still doesn't come on.
