how much 134a is in system

my vehicle fail state inspection for evap and system 2 can these repair be done by me.

will it start out of time

sometimes the A/C blows straight air. Not hot or cold but just plain air then after 20 min or so it will start blowing cold air and seam as if nothing is wrong at all. I was hoping someone could tell me a sulotion without having to spend alot of money to have a service center inspect and repair it.

My wife drives to work in the morning (about a 45 min to 1 hour trip) and listens to the radio like everyone else. Recently, she said the radio LCD panel goes black intermittently. The radio continues to play, and she can change channels although she can no longer tell which button is which. Nothing she does will make the screen come back on - turning it off/on, turning the illumination dimmer knob, etc. Once the vehicle has sat overnight the display usually comes back on the next day, but not always. Once it's back on, however, within 2-3 days it will simply go black again without warning. This panel does not have bulbs, like the dealership service department advisor suggested when we called to ask. I have found a few similar complaints online, but nothing to suggest a fix. The radio is just one function of many contained in this unit, so it seems to me that it's most likely an internal problem. We have seen no codes or warning lights of any kind associated with this problem.

2007 4.3 silverado stalls and start wright back up. no codes,replace cam,crank sensor. coil still stalls, check the rpm signal ok check fuel pressure 60psi at all times. any ideas, i will try any thing at this point thanks bob

Carpet cleaning van. Cleaning unit is van powered by a driveshaft engaged with an electric clutch. Van drives fine with no temperature issue.
When I engage the system it will slowly go to overheat. When the system is engaged the RPMS are ramped up slightly, to about 1800.
Flushed system. Replaced fan clutch, thermostat, water pump. Water is circulating well.
There are no leaks I can find but I am loosing coolant. After it cool down and I open the radiator cap I've lost a lot of coolant.

Bought 2002 TB LTZ 2mos ago, had about 140,000 on it already. Didnt want it, but I was in a bind so I had no choice. Since I got it, the front brakes and rotors had to be replaced because they were shot. The cd player stopped working a week after I got it and now I have to replace the fan clutch. My question is, how long do I have before the transmission gives me problems?, Im aware this vehicle has a history of that too.

i have blinking and sometimes steady oil light on but oil pressure seems to be o k no rattles or knocks

Where is the drain valve for the raditor located at?

When I first start driving my truck and accelerating, their is a puff sound, kind of like when air brakes release the air. It doesn't run bad, just makes this sound. It does go away sometimes, but not always and it only happens when accelerating. Got a new fuel pump last fall - maybe a faulty installation???

i was wondering if anybody had a drive line schematic had a auto repair place redo some u joints and i think he put in a new bearing at where the 2 drive lines meet it doesnt look right the bearing and the rubber gasket or whatever it is is ruined and it looks like when i get under the truck it is missing something in that area where the 2 drivelines meet
