YO CL!!!! now i know some of yall are DIYers like myself and i know some of u had to have converted ur r12 to r134....so my question is where are THE damn A/C port where u hook the actual r134 recharge hose to induce the r134 oil into the a/c system :uh

 

its under the intake pipe on the passenger side

 

yea i believe the one tuterz is talking about is low and 1 next to radiator is high

THANK U SIRS...greatly appreciated

 

Where can you get FREEZE12? I want to know what's wrong with my A/C, but I have no clue where to start! My A/C compressor doesn't even come on, but I'm not getting the A/C blinking light.

 

WHOA HOOOO got cold air now although today in jersey its like 57 degrees

 

You should charge the system through the low pressure port, located on top of the compressor. My '93 SC4's port was covered with a protective black plastic cap.

DO NOT try to charge any system through the high-side port.

 

if your system is low on freon it won't start the compressor.
if you're running a R12 system you can try using freeze 12. you can shoot some in and see if you can find a leak. if you need to repair a major component you might want to consider going to R134a.
