Hi all,

I have checked the archive and I cannot seem to find a threat that answers this issue; my apologies in advance if this was covered and I missed it.

I have a 2004 with dual climate controls. Both sides work fine for heat, but the drivers side will not cool. A/C runs fine otherwise, and the cooling on the pass side is fine.

I have pulled the covers and it appears the actuators are working fine on both sides, as well as the heat control cable.

Any ideas?

Thanks in advance.

Regards,

Detlef

 

Wanted to get back with the group on this. The short answer is that the A/C system was about 12 oz low on refrigerant.

But why was it "working" on one side, you might ask? Looking at the drawings of the A/C system, the refrigerant enters the evaporator section of the A/C system (the coils in the passenger compartment) on the passenger side. Similarly, the heated R134 is pulled away on the passenger side as well. So when the charge was low, the R134 simply took the path of least resistance through the evaporator, that is, through the portion feeding the passenger side. Adding the necessary R134 to get the system volume back to spec provided enough mass flow to force the R134 through the entire evaporator, including the drivers side.

All works well now.

 

Thanks for the update. This reminds me of another recent post.
