There is no expansion valve. There is an orifice tue. It is located in the inlet tube of the evaporator core.
The ac system on a Ram doesn't use an expansion valve. It uses a fixed orifice system.
On that truck you do not have an orifice tube but what you do have is called an expansion block or also known as an H-valve and there are two if you have a dual a/c system..........
A 2002 Ram truck does not have an expansion valve. The ac system uses an orifice tube that is made into the liquid line.
Could be a number of things. Plugged orifice tube/expansion valve. Condensor, evaporator plugged.
Are you sure it has a fixed orifice tube system? Most heavy duty trucks use a Thermal Expansion Valve (TXV) system. In both systems, the metering device (orifice tube or TXV) is located between the condenser outlet and the evaporator inlet.
That sounds like the expansion valve.
I just spent $ 785 to repair AC on 2005 PT Convertable with Turbo...it is an orifice system. Reason for AC failure was failed motor mounts and the engine torque pulled on the AC hoses until they failed and leaked suddenly.
There is no expansion valve. There is, however, a fixed orifice in the liquid refrigerant line from the condenser in front of the radiator to the evaporator core in the HVAC system under the dash.
The accumulator is a component on the low pressure (vacuum) side of an air conditioning system which uses a fixed orifice tube - they won't be found on a Thermal Expansion Valve system.
My manual indicates you have an expansion tube and says to loosen the refrigerant line fitting at the condensor outlet pipe. Remove the expansion tube with needle-nose plyers.
It probably doesn't have one. Every 1990s Ram I've seen uses a Fixed Orifice Tube system.
The metering device. Depending on what type of system you have, this will either be a Fixed Orifice Tube or it will be a Thermal Expansion Valve.
