2003 Suburban AC repair

I don't know if my air condition services were cheating me but I had twice problem with the compressor and after two different checkups both time they told me I had to install a new compressor. and that repairing it was not a good idea.

When you say it is locking up, do you mean that the pulley stops spinning completely while the motor is still running? (this might cause the serpentine belt to burn, come off, or the car to stall or shudder badly)

If so, chances are that either the compressor has already failed completely, OR inside your A/C system is a part called an Orifice tube. This is basically a small filter in the A/C tubing that is supposed to catch small particles and keep them from going into the cooler/evaporator in the cabin of the car. If this little part get's totally clogged, it will cause a back up of pressure and lock the compressor up. This is something that has to be serviced by a shop with specialized tools. DIY on a/c is a bad idea as these systems are SUPER sensitive (even the humidity in the air can ruin parts if you do the job slowly and without the right tools).

If this is your problem, it will likely mean several new parts minimum for your a/c system. If you can afford it, the best bet is to take it to a professional a/c shop. If the compressor has already started to fail and there is metal in the lines, then you may need to replace the whole a/c system as it is very difficult to flush all the metal particles from all the lines and the other parts and any left over metal shavings from a broken compressor will just break the next one as well.

If there is no metal in the lines and the compressor is still in good shape and just the orifice tube is clogged, then you may have caught this in time. You then might have to replace the accumulator/dryer, the orifice tube, and the Freon. The accumulator has a chemical drier in it that if it breaks down is what may travel downline and clog the orifice tube/filter. These 3 parts MAY be a fix for you. Best of luck!

Yes there is > Remove the rear cover and locate the dimple in the pipe it is there when you open the pipe>good luck , hope you have an oriface tube puller.

You need to have the entire system flushed to remove the metal. You'll need to have it serviced by a qualified AC shop.

Hello: It has a smaller serpentine belt behind the larger belt. It also has its own tensioner (these often failed) To replace the belt for the compressor the other belt has to be removed first.

there is either an orifice tube or a expansion valve. both do the same job. however, the orifice tube should be replaced. it will filter small particles from the system and gets clogged. i would also replace the accumulater or receiver/dryer and condensor. if your compressor went bad chances are there is a lot of debris in the system. flushing doesn't always remove the debris. there is much more info on the internet regarding this subject. as well as videos on you tube

sounds like the clutch on the front of the a/c compressor unless the actual a/c compressor is locking up and causing the belt to slap.
the clutch would make a rattle like noise.

Verify that the temperature control inside the vehicle is actually working and not stuck in the hot position.

If the compressor is running and you have the same temp on both tubes the compressor is probably shot. You need to check the pressure on the high side too. It should be around 200.

When you replace the compressor, make sure you also replace the accumulator, orifice filter and flush out the evaporator and condenser. The only moving parts on the ac system is the compressor and often when it fails it will put small metal particles into the a/c system that will cause your new one to fail.

Hope this helps.

if old compressor fail your air condition has to be discharge at dealership or a garage that does ac repair.then the ac lines has to be flushed out before putting on new one. because old one when it fails clutch lock up or compressor fail.small metal particles get in line.stop up orifice tube.you will have to replace orifice tube the accumalator .you will need vacuum pump to pump down air conditioner .to get moisture out of system.you will need a manifold gauge set for air conditioner.ac tools are expensive.it would be cheaper to buy compressor - accumulator - orifice tube. take it to a good air conditioner mechanics.let him put parts on and pump down system.then charge it up.because buying tools to get ac going .is going to cost $475.00 thats the vacuum pump price.you can buy a cheaper vacuum pump that works from air from a regular air compressor you pump tires up with.manifold gauge set causes from $100.00 up to $300.00 for a good set.another thing you have to be familiar with working on air conditioners you put too much R-134 in system you will damage compressor or get seriously hurt.
