• Q: How to service and repair the auxiliary air conditioning evaporator on 2005 Chevrolet Venture?

  A: The first step to service or repair the auxiliary air conditioning Evaporator requires using the tools including a halogen leak detector (J 39400-A). Start the service by separating the auxiliary hvac module assembly followed by the removal of screws securing the auxiliary txv line clamp and finally separating the clamp from its position. Take off the sealing washers from the a/c lines connected to the auxiliary txv and cap or tape the open lines to stop contamination before removal. Remove the bolts which lock the auxiliary txv to the Evaporator core before detaching the txv device along with any sealing washers. Detach first the screws and the actuator of the auxiliary temperature actuator from the hvac module before removing the screws from the auxiliary blower motor housing. You must first separate the auxiliary hvac module case halves after unscrewing its fasteners to reach the auxiliary Evaporator core. The required amount of pag oil must be added to the new Evaporator core during its installation. Reassemble the two parts of the lower hvac module case by inserting the new auxiliary Evaporator core and tightening all fasteners to their correct positions. Screw the auxiliary hvac module case at 1.6 nm torque before attaching the auxiliary blower motor housing and its screws that should be tightened to 1.6 nm as well. You should install the auxiliary temperature actuator together with its screws before final tightening at 1.6 nm (14 lb in). The auxiliary Evaporator core installation requires new sealing washers followed by removal of a/c line caps or tape. Install the auxiliary txv to the Evaporator core while tightening its mounting bolts to 3.5 nm (31 lb in). The new sealing washers should be installed on the auxiliary txv line block fitting then fasten it to the Evaporator core using a retaining bolt tightened to 11 nm (97 lb in). Reinstall the auxiliary hvac module assembly after you attach the clamp to the assembly and tighten its screws to 1.6 nm (14 lb in). Perform a leak test on each fitting through the halogen leak detector (J 39400-A).
