Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
hi i am shannon i will help on this issue
yes there is two
you can test the suction side temp at the rear evaperator
it should be as cold as the front
if it is you need to check the blend door operation
it the rear
a quick test would be to pinch off the rear heater corflow
the rear discharge line is warm at the y off the dryer
you need the test at the rear evaporator
that should be the same as the front suction line
could the orafice be clogged and where is it located for the rear unit
lust like the front .the rear orafice has a filter screen in front of it
did you have a compressor exploistion
no but it was replaced
if not it will be hade to get matiral into the system
will then it could be passable but try thr heater core hose pinch off first. i,ll look up the locatrion of the orafice and post it to you
is the front orafice in the suction line off the dryer before the Y leading to the rear unit
no it should be in the lquid line just before the evaperator
and the rear should be the same
but i will look that up .
i will need to switch to Q&A mode
it will take a few
do you have any more question before i go?
are you going to e-mail or what?
no i will post to this site .but you will get an e-mail when its ready
hear is the rear expansion valve.
