Low charge or too high of a charge.
the low side should read 25 to45 psi at idle.
But, if the a/c behaves this way, there might be a restriction in the orifice tube near the firewall

Good luck to you in fixing this problem.

2003 chevy 1500 ss only blows cold air no heat


Dual climate control on these is not a manual valve adjuster. It is done electronicly with a electric motor on a valve instead of ran by a maual cable. Find this and check the plug for a 12 volt signal. If you are getting a signal replace the valve, if not it could be a blown fuse, cut wire, or a bad climate contol switch.

I have a 2000 Chevy Venture van and the heat when turned on blows cold. For a while it was still blowing out warm air thru the back vents but now it is all cold. The van wouldn't warm up at all e


needs the water system back flushing out, heater being cold is its blocked up some time a few back flushes and forward flushes with a hose pipe should free up the dirt inside, same with the engine and radiator. there are meany videos on you tube to help you understand how to back flush you engie. but do the radiator and engine and heater separate so the muck does not go back into the engine.

We have a 2003 chevy suburban 5.3 vortec it dies when warmed up


Sounds like either Air mass sensor, Air mass meter or finally the EGR valve this is the exhaust gas recycler I would say that is the fault when they start to go this is what they do until finally the car will barely move.

Also I would check all your air pipes for leaks make sure there is no rips or tears in the pipes, The car will drive fine like you say until you ease of the gas to a stop position it **** in to much air and kills the engine. Air faults are cheaper so look there first.

Hope this helps

My 1979 chevy bonanza 4wd. pickup has started blowing transmisssion fluid out the dip stick tube,after the truck warms up a few minutes.thank you albert blair


turbo 350? if so it can be that it is over full or sometimes the gears that are in the tranny that sling the tranny fluid up will get bent or worn and will sling oil to the wrong spots and that will cause your gears to get hot and expand and that can cause it to shoot oil up your dip stick
