07 heater problems

[Chrisb_75]

I have an 07 2.4L camry and now that it's gotten cold out I started using the heater but it only
Blows heat out of the drivers side vents. It blows as hard on the other side it's just bone cold.
I'm not sure if it's an easy fix or not.. Any help would be great, thanks

Could be the heater core on the right side. There are vertical tubes that run across the heater core, and water enters from the side. As a mechanic buddy of mine described it once, over time the end tubes get bits of silicone rubber from the seals stuck in them plus regular corrosion buildup. It progressively blocks off each tube on the farthest end which is the passenger side and gradually works its way back across the heater core plugging up the tubes one at a time. You could try flushing the core or replacing it all together. If you haven't done so already you might try doing a search of this forum for other past threads on the subject.

Or a servo drive to door linkage is loose......
