2017 Cadillac Escalade AC blows warm on one side – rear system works fine, front doesn't
Quote from nickmadison on May 25, 2026, 1:07 pmI've got a 2017 Escalade that's been great for family trips, but the front AC has started acting up. The rear system blows ice cold no problem, but the front vents are only lukewarm at best. The temperature doesn't seem to change whether I set it to LO or 60 degrees. I've checked the refrigerant level and it seems okay. I'm wondering if it could be a blend door actuator issue or maybe a problem with the front expansion valve. I took it to a local shop in Dubai and they said they don't really work on Cadillacs. A friend recommended a cadillac air conditioning repair sharjah shop that specializes in American SUVs. Has anyone here had a similar issue on an Escalade or Tahoe where the front AC isn't cold but the rear works fine? What ended up being the problem? I'm trying to get an idea of what I'm looking at cost wise before I take it in. The car has about 95k kilometers on it and is otherwise in great shape. I'd rather not take it to the dealer because I know they'll charge a fortune just to diagnose. If you know a good AC specialist in Sharjah for Cadillac or GMC, please share. I need to get this fixed before summer really hits because the kids are complaining every time we go anywhere. Thanks in advance.

Quote from liammitchell on June 29, 2026, 11:16 amTemperature not changing whether set to LO or 60 degrees rules out a simple blend door actuator fault. That symptom points directly to restricted refrigerant flow through the front evaporator circuit specifically.

Quote from aaronrichardson on June 29, 2026, 11:17 amGM dual zone systems on the Escalade have independent front and rear expansion valves which is exactly why one circuit can fail completely while the other works perfectly. A Sharjah specialist familiar with these American SUVs will know that immediately.

The cooling system is essentially identical across these trucks and any experienced American SUV specialist handles it confidently.

Quote from trevorsullivan on June 29, 2026, 11:17 am95k kilometers on an Escalade with front expansion valve issues is common enough that a specialist will have seen this exact fault multiple times. Getting it diagnosed properly before summer peaks with kids in the car is absolutely the right priority.
