did you have r-12 left in the system before you added the 134a?

you may want to look in to that then. it was a R-12 system before no?

I never played with the retrofit in eg's before but some models required changing a few things like the orifice tube or low pressure switch. due to the pressures are slightly different in 134a vs r-12 system

these are some very basics to retrofitting to make it work properly aka no noises or it actually blow cold as you want it to.

my cb7 when i did the basic retrofitted with new fitting and had the system completely drained and refiled with proper oils and r134A it did not blow cold it blew just cold enough to say it was colder then the air outside and I would need new adjustable low pressure switch and possible orifice tube. and found out I had to take the dash out to get at it and didn't bother.

- Fri Jul 09, 2010 4:21 pm #203857 he wouldnt have been able to put the freon in if it was a r12 system the fittings arnt the same

and the vibrating is from the compressor trying to compact the freon but cant cuz theres too much.

please don't tell me you just let it out in to the air if you did you could be fined

take it to a garage with licensed air condition license and have them look at it. it may be something plugged to so the freon may just be pressurizing the high side

You wouldn't believe what people do to try and get stuff to work.


it may also have been retrofitted before.
