My 2001 GMC Yukon is only blowing cold air in the back.
Whenever my mom turns on the a/c, cold air
only flows through the back seats. In the
front, it only feels like air is coming out. It’s
not hot or cold, just air. We put in EZ Chill
and it as made the air a bit cooler, but it
hasn’t totally fixed the problem. Does anyone
know why this might be happening, or what
we could try to do to fix it?
