TRUCK WONT LIFT

IV GOT A BIG PROBLEM MY TANK IS FULL BUT WHEN I HIT THE SWITCH MY BLAZER ONLY RAISES ABOUT 1 INCH

it can be a number of problems. Check that all of your wires are hooked correctly, switchbox F-up, if its cold the valve might of frozen or your airline, i'm not an expert but try checking these things, if thats not it than it might be that you just need a new valve or something. Good luck

are none of the corners/sides lifting?

how much psi is in your tank?

Tank builds up enough pressure to shut off the compressor but truck will only lift 1/2 inch, no more.

you're having problems with front or back? What size bags do you have?

It might ba a faulty pressure switch.

Do you have a gauge that has a tank pressure reading?

I second this....Get a gauge on the tank or just bypass the pressure switch and see what happens.

maybe you have alot of water in your tank taking up the air space. some guy came to me saying he only got 1 good lift before comp turned on but used to get about 3 lifts. he had a 6 gal tank & it had a shitload of water in it, i drained it & worked better. havent heard from him in a few months

where do you live? Is the temp. cold (below freezing). The water in the lines and tank could be frozen causing problems.
