Cadillac Escalade Rear AC Problems

In 1999, Cadillac introduced the Escalade -- a luxury sport utility vehicle (SUV). The Escalade features several elegant extras and creature comforts, including rear air conditioning (AC). Occasionally, as with all AC systems, issues can arise in the Escalade, and troubleshooting them can be a breeze if you know what the common issues include.

Control Module

One common issue in the Escalade's rear AC is a malfunctioning control module. If your unit is blowing warm air or does not engage at all -- the control module may be the culprit.

Blower Motor

Weak ventilation or no ventilation at all is a symptom of blower motor failure. The motor has been recognized by Cadillac's technical service bulletins as a potential issue.

Blocked Vents

Vents can occasionally become clogged or blocked, keeping air from flowing freely. Use a flashlight to peer inside the vents to locate and remove any obstructions.

Repair Cost

Some repairs, since they are recognized by Cadillac's technical service bulletins, may be covered under warranty or recall. If your vehicle is out of warranty or is not covered, expect to pay about $100 to $150 for control module repair and $200 to $250 to correct the blower motor (as of February 2011).
