HEATING AND COOLING SYSTEM

[brockstar15]

Hey guys/gals I have a question. What are ALL the parts of the heating and cooling system on a 88-94?

I know these:
Radiator
**Radiator Hoses
Thermostat
Heater Core
Heater Valve
Blower Motor
**Blower Motor Resistor
**Heater Hoses
Compressor
Orifice Tube
Accumulator
Condenser
**AC Lines
**Coolants

Are there anything else that i'm not thinking of?

Expansion valve, evaporator.

They're on the 88-94's?

If it has A/C. It should have them.
Expansion valve is for the Suburban auxiliary A/C-heater assembly.

So since I have a single can Sierra I don't have an expansion valve?

According to Alldata, no expansion valve. Orifice Tube is the expansion valve.
Your truck does have an evaporator core.

Sorry to miss lead you.
I had to refer to Alldata to give you an accurate answer.
