GMC SIERRA AIR CONDITIONING PROBLEMS IN EDMONTON
The 2014 to 2017 GMC Sierra 1500 (also Yukon/Yukon XL 2015 to 2017) has a known issue: air conditioning failure from a cracked “combi-cooler”: the combined A/C condenser and transmission cooler cracks from thermal stress and leaks refrigerant, so the A/C blows only warm air. The defect was the subject of an 8-year federal class-action lawsuit alleging GM knew about it.
A/C failure from the cracked combi-cooler is the air conditioning issue these trucks are known for, and it often comes up with Sierra brake problems. The symptoms below cover what the failure looks like, what causes it, and what we check before recommending a repair. If your Sierra shows any of these symptoms, have it checked before the problem gets worse.
Auto Imports diagnoses and repairs these GMC concerns in Edmonton. We start from the symptom you describe and confirm the fault before recommending any repair. The details below describe what is known about this issue on these models. Pricing is approximate. Call 780-431-2828 or message us for an accurate estimate for your vehicle.
COMMON SIERRA A/C SYMPTOMS
The known issues identified for this vehicle include:
- A/C blowing warm air despite correct settings
- Refrigerant leaking from the front condenser area
- A/C performance degrading over weeks as refrigerant escapes
- Compressor cycling rapidly or not engaging
The crack in the combi-cooler is found with UV dye; our car A/C repair service confirms the leak before any parts are ordered. Final pricing depends on diagnosis, model year and repair scope. Call Auto Imports for an accurate estimate.
WHAT TO WATCH FOR
Model-specific concerns and service points:
- Failed A/C also means failed windshield de-fogging: a winter safety issue in Edmonton
- UV dye testing can help identify the crack location
- The combined cooler design means transmission cooling is inspected at the same time
- Verify whether any extended coverage applies before paying out of pocket
Mileage is a risk indicator, not a diagnosis. A component can fail earlier or last considerably longer depending on maintenance and operating conditions.
HOW AUTO IMPORTS DIAGNOSES THE PROBLEM
Different faults can create similar symptoms. Our diagnostic process can include:
- Full vehicle scan for stored and pending faults
- Live-data review under the conditions that reproduce the complaint
- Visual inspection of the affected system
- Leak, pressure, electrical or mechanical testing as required
- Verification of the exact engine, transmission or system configuration
- Written repair recommendation based on the confirmed fault
Professional vehicle diagnostics help prevent replacing expensive components based only on a common failure pattern.

GMC SIERRA AIR CONDITIONING PROBLEMS IN EDMONTON FAQ
Is there a recall on the GMC Sierra 1500 for air conditioning?
Some model years were covered by manufacturer recalls or special coverage programs. Check nhtsa.gov with your VIN to see whether your vehicle is affected.
What should I do if my GMC Sierra 1500 develops these symptoms?
Book a diagnosis before replacing parts. The same symptom can come from several different systems.
Are the repair prices exact?
No. Any ranges on this page are approximate. Message Auto Imports for an accurate estimate after the vehicle and required repair are confirmed.
