what does it mean when the clutch for the AC compressor goes on and off while AC is on? i just recharged it and i don't think it's suppose to do this. anyone has this problem...

I believe it's supposed to do that, if not you could burn out the compressor. I think it actually runs more efficiently by turning on and off.

Someone with more knowledge like JetJock will chime in I'm sure.

i had the temp set to 65 (lowest setting) and it wasn't even cold yet... it clicks on and off... it would click on for 2-3 seconds and then clicks off... i refilled it with 3 12oz cans of R134... is this too much?

That is normal. The Clutch cycles for a number of reason. IJ (Ian) is correct, and Nick is also. It will also cycle off if the Highside Head Pressure gets to high.

Questions.
1) How long was your system open to the air?
2) Did you replace your reciever/dryer?
3) Did you evacuate the system before you filled it?
4) Why did you think 36oz of r134a would be a good idea in a system designed for r12?

My theory based on your comments so far.
1) You have water in your system.
2) You have either too much, or two little freon.
3) You have the wrong type of freon.
4) Your screwed.

I suggest the following.
1) Turn off your AC.
2) Go to a shop that services AC.
3) Tell them what you did. (Try not to notice the laughter at your expense.)
4) Ask them to replace your reciever/dryer and evac and recharge the system with R12. (They will have to flush the system out most likely to remove the wrong oil/freon you put in there.)
5) Pray that your compressor is not going to die an early death, and then enjoy your now working great AC in the summer heat. (And it makes your defroster work so much better in the winter time too.)

Good luck.

no i did not. the system was completely empty... i did this what i had to remove the motor.

first off that is your first mistake.

You never ever put refrigerant into a system without pulling a vacuum!

<-- wonders how many A/C less supras are running around in 100 degreee weather actually ENJOYING it!!! :)

I come from a land down under
I don't think they're bustin ya balls it's just a bit frustrating when people don't follow the accepted norms in servicing a system then have "issues"

Vacc it out refill it by weight and hopefully it comes good!

Best bet is to evac it out then fill it. One thing to note especially being that you are using R134A is to fill it based on pressures not by weight. R134 actually causes higher high side head pressures and needs to have a reduced volume by around 20% to 25% less then what the original volume of R12.

Sorry for saying that it was normal for the system to be cycling in my last post. I some how over looked your post about that it wasn't getting cold yet and that you put in 3 cans of R134. Just to note though, a properly done system will cycle every so often, especially in hot and humid climates.
