Gotta love the summer A/C threads

I've got a 2K 3.5

I've just charged my system... something I've not done before. I used a manifold kit and when I started, it was running 30lbs low and 175 high. I got it to take a can and a smidge of refrigerant. Now its running at about 35 low and 225 high. It will go between cycling on and off and actually staying engaged for awhile before disengaging and equalizing.

There was a change in temperature for sure, but the drivers side is still warmer than the passenger but it's comfortable.

I doubt I have a leak of any consequence since the starting numbers were from it not being used at all for a good year and a half because the blower motor died, but was just recently replaced. It did not cool great before the blower went out, so I can assume it was undercharged then as well.

Does anyone have a temp/pressure chart so I can guestimate if I need to add more to get the temperature on the two sides to balance out, or if there is something else I should check?

I'm also sure that I have the issue with the manual climate control AC on/off switch problem, but if I push it enough times, it will stay engaged unless I push it again, and then I have to keep pushing it a while to get it to just finally stay on again.

What you guys think?

I have the same prob and i am a auto tech and still cant figure out what it is...when/if you find out please e-mail me at hotstud252005@yahoo.com......thanks...dave

Make sure each time you charge your system to ALSO lube your A/C compressor with the needed oil to prevent Black Death from occurring. I learned the hard way.
