A/c not blowing cold on 1999 volkswagen jetta

Went to add a can of 134a, and when I check the pressure on the guage it was at 30. On the diagram it states not to go over 45 or you will over charge the system. It still does not blow cold and hardly took any of the 134a. I then purged the system to start over and before even finishing one can, it is above 45 and still not cold. It seems like it still needs more 134a but the pressure is already maxed out. One can is 368 grams and on the firewall it states it should hold 700 grams. Do I continue to add more even though the guage reads high. The compressor seems to be fine and kicks on and off when I turn the air off and on.

Check your cooling fans. The A/C cooling fan may not be working.

2002 VW Jetta 1.8T has a leak somewhere.Need diagram

Bring the car into a repair shop and have them pressure test it for leaks or you can purchase a pressure tester make sure you get the appropriate adapter for your cars radiator filler neck or resovoir, and check for leaks yourself. Make sure the car is cold and there is the appropriate mixtiure of coolant and water in the system, prior to pressure testing. Also do a visual inspection of the cooling system when the vehicle is cold and look for leaks.

On my '83 Volkswagen Jetta that I am trying to get running-- It will run for about 3-4 seconds and then stall. Any ideas?

You have the bosch CIS fuel injection system, it's a cold start issue which may point to either a bad fuel pump check valve OR an issue with the warm up regulator.

You will need a special $$$$$$ fuel pressure guage to check ALL the pressures and then you will find the exact cause.

VERY expensive parts and labor is just as expensive.

What would make the AC clutch turn on an off repeatedly, approximately every 4 seconds on an 99 chevy Suburban 5.7L 4x4 LT? Only blows out hot air

low freon soumds to me.. jump out the low pressure cut out switch near the dryer...or jump clutch relay in the distribution center. with clutch ingauged hook up guages to check low and high side pressures... also easy trick go to auto store get a can of 134a freon with hose and add the can the clutch should stay inguaged longer and longer as you fill the sytem... with clutch inguaged rev motor up to 1500 the guage on the hose should be around 35 to 40 pounds if low add more

I have a 1999 Chevy Silverado, the a/c works fine for a while then blows hot. If I turn a/c off for a while, it will cool again, but after a little while, will blow hot. What could it be?

ok sounds like you may need to add a can or two of 134a freon which isnt too expensive you will have to have special gauges to make sure of the correct amount of refridgerent if you over fill the system you could bust a line on your condensor or worse screw up your ac pump but you can find 134a at all your local auto parts stores when you put the freon in you want the vehicle to run and the ac on high all the way cold and when the can is punctured shake it constantly until empty one way to cheat without using gauges is to hold you hand on the low pressure line when it gets cold that means you almost got it done make sure you do not connect the can to the high pressure side because you can blow up the can in your hand i would start with one little can then go check to see if you have cold air if its not frezzing cold you can put another one in until you are satisfied if you need anymore help just ask :)

Your AC is low on refrigerant; The AC compressor needs a minimum amount of regrigerant to run. If and when it does run (while low on refrigerant) the air coming out of the vents will not be cold. The refrigerant you require is R-134A and is available over the counter but if you are the least bit unsure as to how to add refrigerant, taking it to a garage that does AC recharging would be your best play. If you want to try to add refrigerant on your own you will need the following, 1LB can of R-134A, an AC hose adapter to deliver the refrigerant, and preferably an AC pressure guage to ensure you are not overfilling the AC line which will damage the system.
