If someone said the freon is leaking out, then you have a leak that needs to be repaired. Every connection in an AC system has a seal. AC systems work under very high pressures. When a seal goes bad, all the freon in the world will not stay in.
They sell kits with all the seals just for this purpose. I'm in AZ, so I can't help you. Plus, I'm working on the AC system in my wife's car right now. What you need is a reputable shop that can do the work for you. The whole system needs to be gone through. It will cost money to get it done correctly. And you should have a professional do it, not some shade tree mechanic. Good luck. I know what east coast summers are like.
Sorry I don't have a better answer.

P0452 is related to the Evaporative Emissions Control system and has nothing to do with the 4WD system.
The P0452 may be something as simple as a loose or bad gas cap.
The 4WD system is somewhat complicated and requires more diagnostics.

I guess my first question would be are you sure you got the right replacement belt ? And are all of the pulleys on straight ?
Is the belt slipping, or coming off ?
Was the original belt giving you problems ?

Hello: The best to do is have the system checked with a scanner to get the code but most likely you have a pass-lock system problem. The whole lock cylinder will have to be replaced along with a new key.

You may have to loosen the engine-to-frame mounts and slightly raise the motor to access these. Always use jack stands when lifting something as heavy as the engine for safety.

I know the problem with the key getting stuck is because of a bad cylinder, but there is a key release button under the ignition.

8 - 12 quarts depending on how well drained it is

remove the spark plug and see if it is wet. See if it smells like gas. Put the plug in the plug wire and crank the car to see if it sparks. If so, get a compression gauge and screw it into the plug hole and crank the engine. Good compression 100lbs or better. If good suspect injector.

Are you the guy who had P0302 code.P0453 is the fuel tank pressure sensor is reading to much pressure to high that would explane why it would pass emissions Iwould check a part called the canaster vent soleniodif its stuck or cloged you would have a high pressure level in the tank it sends fuel vaper to the charcoal canaster from the tank where it is stored until your at highway speed then the canaster purge sloeniod opens and the vaper is burned in the engine. Ihave a 96 blazer and had a simaler problem but i was getting P0304 # 4 cylinder misfire although i had to replace the fuel pump to but that was part of the problem.You need to remove the spare tire and its on the top of the frame cross member above the tire mount check the filter thats in it and you can check to see if it works by jumping 12 volts across it it should click you will feel it move if its good. Ican't say for sure but i can't see the vehicle and this makes a lot of sence to check first and likely will clear up the problem it cost about 30 dollars for a new one

There are several things that could be causing this problem, from a bad spark plug, igntion wires, distrubtor cap, injection , no compression in that cylinder. Try the simple things first = plugs, wires, cap etc. a bad note: these are known to have the injector "poppets" fail with no warning. Go there when all else fails. good luck.

the actuator is located on the lest side of transfer case and it usually is the sensor inside that fails it is cheaper to just replace the sensor but it takes a little more technical knowledge to do your indicator on the switch probably just flashes.

Have you charged or replaced the battery with a new one?

Also, make sure the contacts at the battery are clean and shiny to start with.

1998 GMC Envoy | Answered on Nov 03, 2010 | 46 views


It is possible that you may have got defective parts, unlikely but possible. More like though, would be that you have a draw on the system, one way to tell if you want to know for sure is to make sure the battery is charged really good and unhook the battery overnight. In the morning hook the battery back up and if your vehicle starts the batery probably has a draw from a electrical part on your vehicle that is not shutting off properly causing a drain on your battery.
