Is the compressor engaging (clutch turning with pulley, or clutch stationary)?
If not, go ahead and shoot that can into it, and see if it comes on. You can also jump the wiring plug on the low pressure switch and force the compressor to run if it's real low, but don't allow it to run very long this way...if it refuses to accept gas or the pressure doesn't begin to come down within a few seconds of charging, unplug it.

Jeff, Thanks for quick reply.
Compressor is engaging. Should I be checking the pressure again on the low side with A/C running? I checked the radiator fins, I think it is dirty, How do I clean it. Also both fans kicked in. Both pipes High pressure and low pressure at the compressor side were hot to the touch. At the fire wall high pressure (smaller diameter) pipe was a bit cooler. What is my next step? Do I still need to recharge?
Another question, Assuming the actuators are bad both driver and passenger, then there should not be any change in the temperature of the blowing air from the vents, right? I played with the thermostats to see if the passenger side remains the same when moved to extreme heat side, blowing air was hot. Now, I think it may not be the actuators.
Thanks again.
