ok you have all help me out a lot from reading posts and posting and you replying. From posting yesterday , i have put the fuse back in for cigaretter. and now the compressor turns on. now the issue is not getting cool.

The A/C dude who was going to charge my system said the system pressure was fine. so if im not leaking and I have good pressure what else can I check now?

compressor wheel is turning . You can see it turn, logicon works (got the rebuilt one from ICEMARK). I mean when you hit the button you can hear things turn on and and rpms drop and rise.

any suggestions?

thanks again

 

Pretty basic - check the sight glass while the system is running.
See that your gas is not foaming at the accumulator.
With R-12 it should be clear.
With freeze 12 it should show just a few bubbles.

Feel the in & out lines to the evaporator at the firewall for a strong temperature difference.

 

ok this is what you do...remove it then just ride around with the windows down. you will get used to it.

 

been doing the whole window thing for a while now. working in a business suite environment and having to wear my suit and tie everyday makes it very hot. There are times when i get in the car and im already sweeting. so it would be nice to have a cool car in a matter of minutes.


also if there is not temp diffrence in the lines, does that mean the freon is low?

 

Could be, and most likely. Could also be a compressor that's not compressing. If the refridgerant is too low, the compressor will not engage due to a safety switch, in order to protect the compressor. If the compressor IS engaging, checking the refridgerant amount is the next step. Check the window in the dryer as stated in one of the posts above.

 

I would check some of the controls, does the vent temp change at all when you adjust the temp controls? Maybe theres a flapper door stuck open, or shut?.
Also does the rec button affect the temp at all?, should get colder on recirculate.
Did your ac guy check the pressures running, hi and low?

 

ok puitting ind the fuse to the cig. work great. compressor turns now. I can hear a hissing sound in the compartment now. but still no cool air. I looked in the window your talkint about above and could see clear liquid stuf and kinda looked like it was somewhat bubbling but still clear.

I dont think any of the vents arestuck cause you can change it to legs to face to both to windows.

any other ideas?

if he checked it with the compressor not turning , would he have gotten an inaccurate reading perhaps>? he checked it but at that time the compressor was not working.

any other htings to check

 

If he checked it not running, and it had not been run recently, the pressure would be only the static pressure. It could have half the needed amount or twice the amount, the pressure would be the same. And if the car had just been turned off the pressure readings still wouldn't be accurate, you need to have the car running to get readings.
134a high side should be 2.2x the air/ambient temp, I think.
Not sure how to use the sight glass, Sureshot sounds right.
What is the refrigerant your useing?

 

he checked it with the car warmed up and a/c on and temp on cold and full blast. at that time htough the compressor was not ingaging.

I guess I will go back and see him to have him check it again sence the compressor is turning now.

anyone else got any ideas? same for the window. from what i can tel its clear with a bit of bubling on top.

 

This was an "AC" guy who checked the pressure with the compressor not engaged? Find a knowledgeable person to do the work.

 

So - with the compressor engaged and a clear sight glass, the evaporator in & out should be hot & cold.
If not, only the pressure readings will tell why.

Possibilities:
Clogged orifice
Stuck expansion valve
not enough refrigerant
too much refrigerant
totaly worn out compressor
air in the system
bad thermo sensor (letting the evaporator ice up)
stuck air door blocking the evaporator path
pinched pipe somewhere
