You have a leak in your A/C system. You need to take it to someone that has the tools to find it and repair it.

If you are going to replace your shocks, which is actually struts, you need to take it to someone that knows how to replace them. They are a little dangerous if you don't watch it. Don't buy the cheepest you won't be happy with them. But you don't have to buy the most expensive ones either.

The side window you can find at your local salvage yard. Way less expensive than a new one from the dealer.

I'd have them checked first to determine if it is actually the shocks, or possibly just a loose or cracked line, which should be a pretty inexpensive fix. If it turns out to be shocks, weigh it out then.

SOURCE: 2003 Buick Century - window problem

I've had a similar problem with my 2003 Buick Century. In my case, the driver's side front window one day went up and would not come down. I knew that the switch was malfunctioning by sticking in the up position since the window continued up despite the fact that Iet off the switch when the window was half way up and it continued going up. I had to pull over and pull the master switch assembly from the door panel and unplug it to prevent the window motor from being damaged by the constant power feeding it after the window was up. Basically, it would have burned the motor out. I cleaned the switch and it now works fine most of the time. I still need to replace the assembly. Not sure this is the reason in your case. I would check the back window and see if it goes down with the switch on the back door panel. If it does, then you are having problem with the master switch assembly on your front door panel. Moisture from rain from the window being down during rain or dirt may have corroded the switches' contacts.

  • Assumed your AC unit is OK, but uneven temperature distribution. Try to throw the heater on an off severtime. A sticky valve on the heater would cause similar problem.
  • Observe the RPM while parking your car. While the AC cut in cut out (or turn on an off). If it cause no load on the engine. The freon may be low or the compressor is bad. In this case only the intake side of the evaporator is cooler than the other side.

SOURCE: 2003 buick lesabre AC problem

You have to find the motor that controls the blend door and open it manually to find out which one is bad there are 3 blend doors on the HV/AC system one will be where the heater core is. The other will be between the vented air and AC? heating system then the third door will operate vents in dash and defrost condition. If you have someone operate them AC system heating system and watch the blend door motors, the one you find not moving will be the one that has the problem. They have vacuum and electrical motors, if it is a acuum motor you can move the door manually with your hand, if it's electric you will have to disconnect the rod by removing the pinch clip off of the rod.

Rear shocks are stiff, and it rides very hard.

Rear shocks are the Air Shocks and they need compressed air in order to work properly, so you have to take closer look at your air management system.

Why does my ac quit working in traffic

At 30 miles per hr you get enough air flow through the condenser coil to keep the A/C cooling. Check the cooling fan at the radiator. It should run when the A/C is on no matter what the engine temperature is. When the freon is low enough to affect cooling it will do the same in traffic or on the road. Engine coolant level has no affect on the A/C,.The condenser is forward of the radiator. You didn't say the car was running hot.

Compressor isnt turning at all dont know if i need new one or if i need new clutch how can i tell

The pulley on the compressor is always running when your engine is running, but the only time
it compresses the freon is when the clutch engages, if the compressor's pulley was not turning,
it would have already snapped a fan belt or your serpentine belt. voltage runs from your fuse box
thru your air condition switch on your dashboard to a low pressure switch that is located at the
accumulator a long cylinder,close to the firewall under the hood or close to the condensor, front
of the car. the switch detects freon pressure in the accumulator, if there is freon pressure, the switch
will stay closed and allow voltage to go to the compressor clutch to engage it and compress the freon,
if there is no freon pressure the switch will open, and there will be no voltage to air compressor, its a
saftey switch to keep your compressor from getting damaged.its possible that the switch could be bad
it may not have voltage at the switch, or it may be open because there is insufficient freon pressure.
check and make sure there is freon in the system.check for voltage at the low pressure switch if you have freon in your system and voltage at the pressure switch, set your ac on high, pull the molex off
the switch, and jump it out with a jumper wire, if the clutch engages and your car starts to cool, just
replace the switch. if the clutch engages but does not cool, then your ac system has some blockage
in the lines. if the clutch does not engage at all then it would be the compressor clutch. good luck!

Will the a\c compresser work if no freon

The answer is no. The unit is protected by a switch to prevent it from not starting with no or low Freon. Freon contains lubricating oil. So --- No freon , no lubrication, compressor will seize up.
Kind of a good thing. Saves the compressor if the unit runs out of Freon.

I bought a suspension lift for front and back... I am having a hard time getting my shocks to compress enough to install it..the people i got it from said I can use my factor shocks, help..

It depends on the amount of lift, but shocks don't take kindly to changes in the distance they have to travel in. They will at some point pull the mounting brackets off the truck. I have used this trick before. Mount the top of the proper shock on the truck and use a floor jack to raise the bottom of it to the mounting bolt height, then tap it on with a hammer.It will raise slowly because you are moving fluid through restricted holes but it should go if it's the right shock. Hope this helps.

96 suburban air conditioning blows out cool in front hot air back

Am investigating same problem. Download the free technical manual and you can find a diagram for the air mix door. If this doesn't shut you will be getting lots of heat through despite the cooling of the Aircon. I don't know how to get at it or fix it but it describes how to run diagnostics - you don't need specialist tools for this. Also a blocked pollen filter probably won't help.

Compresser runs battery dead

There may be two compressors. One for the air conditioning that runs off a belt bolted onto the engine. No, you don't need it if your windows will go down this summer. As long as it turns, it doesn't have to compress. (You can have other things wrong with air conditioning also). If there's absolutely nothing else being driven by that belt, the belt could even be removed if the compressor is frozen. That would save a little gas if that can be done. There might be another compressor, a little thing mounted on the drivers side inner fender well on some cars. It's for the rear shocks if the car has that kind. If the car still rides and handles ok, you can live without that guy too. Sometimes you replace the shocks with regular ones.
