Hi Every one
I have 2006 GX470 with Nav. A/C does not blow cold from driver side , I replaced Air mix servo, but still same problem. heater is working both side . any body has any Suggestion.
thanks

 

Had the same problem in my GS. It was low on freon filled it up and now it's good.

 

thanks
I will try to put some freon , let see if works. but when I change the temp of passenger side to hot and cold of driver side ,then it should work . ..

 

has expansion valve sticking, replaced expansion valve , a/c cools good.

 

In the spirit of simple things first. Mine was doing this until I realized I had accidentally unlinked the left and right sides and the right side was set warmer. If you already reached parts, I'm sure you already checked this?
