2006 Buick Rainier Parts Questions & Experts Answers

• Q: How to replace the evaporator core in the HVAC module assembly on 2006 Buick Rainier?

  A: The procedure begins with HVAC module assembly removal before the HVAC module assembly screws are extracted to detach its two parts. The installer should know that hidden screws lurk beneath foam insulation. The HVAC module assembly requires separation before removing the evaporator core from it while also removing the seal between its two assembly halves. Start the replacement process by laying the seal between the two parts of the HVAC module assembly. The refrigerant oil addition to the evaporator core must be done when replacement occurs while the correct amount of oil must be checked against the system capacities. The evaporator core should be positioned into the HVAC module assembly before reassembling the HVAC module assembly while ensuring proper placement of the two case section seal. Follow this up by screwing the HVAC module assembly halves together before final installation when tightening screws to 1.9 N.m (17 lb in).
