A 1999 Ford Mustang has r134a in the air conditioning system
I believe it is around 3 1/2#.
Freon is added in the low pressure port of the ac system. It is under the hood close to the ac drier.
I have a 1993 olds cutlass ciera and the AC fan relay is the one in the middle on my car.
You have a leak somewhere in the ac system. A dye can be injected into the system and with the use of a black light and special glasses the leak can be detected so repairs can be made.
The low side service port to recharge the AC on a 1997 Olds Cutlass Supreme is at the rear of the engine. It is close to the firewall.
How much freon does 99 Tahoe with rear ac hold
The best type of filters for ac systems are dust trap filters they are known to filter out more dust and other things.
Blown fuse, bad motor, bad blower motor switch, or a defective Blower Motor Resistor Pack.
