Just had new compressor and dryer put in. Front air works fine. But rear air does not blow, at all. Put on new blower motor and relay. Still nothing. Hot wired blower and air coming out is not cold. Please help.

If relay clicks put a test light on motor see if it lights if not try jumper relay term to moter see if it comes on. If there was debris in system the rear unit will not cool no freon can pass into evap. Need to replace valve.
