Heater Core

Good evening,

I've owned five Jeep Wranglers over the past thirty years. My last two recent Jeep Wrangler Sahara's - 2010 & 2012, both heater cores went out on me. Same exact issue with both - only blows luke warm air to the passenger side and cold air to the driver's side.

I've tried to do some research, but unable to really track down.

Is this a known issue with Jeep Wranglers through certain years?

Your feedback is greatly appreciated.

Thank you,

Have you tried back flushing the heater core?

Hi Aleekat,

Unfortunately, I don't have a Mechanic's skillset and or the knowledge to answer your question with much confidence.

From what I remember, the dealership did try a back flushing on the 2010, but that didn't help.

I ended up trading it in(not because of the heater core) for the 2012 that we currently have.

Was hoping not to run into the same issue, but unfortunately we have.

I don't know what the general life expectency of a heater core is and maybe it's just that - end of life.

I've just never ran into this issue with any other vehicle.

Thanks,

they show you how to fix blend doors yourself

As brcidd mentioned it likely isn't heater core but blend doors.

There is a box underneath the dash that controls how much heat and where it goes; on our 2011-ish liberty, we had similar issues.

Replacing requires removal of the dash so it's not cheap; the unscrupulous dealer we took it to said they replaced the unit but they did not... so if it is not a DIY item for you, make sure to find a trustworthy repair shop to do the work.
