[QUOTE="Meatwood Flac, post: 428898, member: 19640"] I’m having a similar issue. 2011 jk sport. I’ve just recently (as of 2 hours before posting this) had a coolant flush, dye test and Coolant refilled, new thermostat and Thermostat gasket with a new radiator cap. Water pump is about 8 months old and working fine. My problem is that, depending on the day, My driver side vent and floor vent can be anywhere from 10 - 30 degrees cooler than my passenger side when turned to heat. In the winter time this equates to basically no heat on the driver side. The left middle vent is lukewarm and the farthest vent on the driver side is always colder than it. I’ve checked the blend door actuator for proper function and it moves perfectly. My heater core hoses are both hot to the touch in the engine bay before running into the firewall, and the metal pipes that run in and out of the heater core are only about 5 degrees different, ranging around 135 degrees (checked with an IR thermometer from behind the glove compartment). There has never been a coolant smell and I can see no signs of a heater core leak. What else could this issue possibly be? I have been told by a separate mechanics shop last winter that the heater core needed replaced, but in lieu of all the evidence I’m beginning to think that they have suggested this simply because they can’t figure out another possible issue. ive run out of ideas and have searched countless forums. My engine doesn’t overheat as of now, and If it is the heater core I’d rather buy a snow suit than pay to replace it since the only symptom I’m experiencing right now is poor heat on one side. AC blows the same temp in all vents when on full Blast if that is relevant. Send help. [/QUOTE]
