where is the expansion valve located
No, a 1995 Chevrolet Suburban does not have a carburetor. The carburetors were changed in 1995 and replaced with fuel injectors.
you can't
Most likely the rear expansion tube or valve is defective.
It is attached to the back wall of evaporator. You have to remove the glove compartment, blower unit and evaporator to get access to the expansion valve.
4L60E if it is a 1/2 ton. 3/4 ton will have a 4L80e in it.
Possible blockage in the rear air units expansion valve. I just replaced mine for the same reason.
In one of the valve covers there is an elbow with a rubber hose attached. The elbow is the PCV valve.
The expansion valve is located next to the evaporator coil in the rear passenger side, just behind the fender well. you will notice the air intake or (return air) grill has slots and this is present just as you open the back door or gate 1st thing on the right.

The valve is at the front of the engine just behind the A/C Compressor. Its just above the thermostat. Be careful as for some unknown reason GM has designed this valve without polarity.

I believe you mean suburban, It has a 4.3 L engine with a timing chain. Chevrolet didn't badge the Tahoe until 1995.
