Question about 2003 Kia Sedona

Ac not cold

I have an 01 Olds silhouette. My ac isn't cold at all so I bought one of those recharge cans and the pressure was down aroung 10 psi so I put in the can and it brought it up to 25 psi (barely in blue zone). Air was colder and ok when moving but when idling the air is well lets say not hot but def not cold. So I got another can to put in but when I hooked it up now the pressure is bouncing between 30 and 40 psi. I checked out other vehicle and when you turn on ac the low pressure line gets hold right away, the van's line doesn't get cold at all. Should I add the 2nd can and see what happens or take it to a professional?

Do not over charge the system, your going to do A/C compressor damage. The low pressure side should be 40psi to 50psi and the high pressure side should be 150psi to 200 psi with the A/C on the highest position. You may have a bad valve in the A/C system and need it serviced professionaly. Good luck and hope this helps. Keep me posted, be glad to help.

Add about half of the 2nd can. Look on hood or radiator support to find the sticker that tells you how much the ac can hold.

1999 Ford Ranger AC low side pressure reads 100 psi


Was the a/c compressor running when you got this reading?

Ac blows cold air for about 15 minutes then starts blowing warm air then starts blowing cold air again freon is full


Freon is not full. If it goes back and fourth it is pumping then reaching a low pressure on the low side below 35 psi. Pressure while car is off should be pegged. Check at idle should be around 50 psi and 35 psi at 2000 rpms.

Good luck. If problem persists evac system replace dryer and recharge.

How do i recharge my air conditioner in my 2004 Volkswagon R32 . The a/c condenser goes on but the air does not get cold. i can buy the a/c charger at walmart but dont know where or how to charge it......


1. check your refrigerant pressure and if the reading is below 20 psi then ur gas is less
2. locate low pressure service port that reads L
3. start engine/ turn ac on
3. recharge gas to max pressure between 20 and 40 psi max.
4. feel the low pressure line if its cooling while ac is running...the job is done...

Where is the low side port to recharge the AC on a 2000 Olds silhouette?


Follow hose from compressor or firewall & look for a valve sticking out with a plastic cap on it. Low side is the bigger diameter hose & piping.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
