Help, long trip coming up. Heat only on drivers side?
 

I'm only getting heat on the drivers side vents, passengers side blows cold. Any Ideas whats going on ? :confused:

Any help is appreciated.
Thank You

Is it a Euro version by chance by that I mean a Grey Market Auto with dials for heat left and right instead of a center push button Auto Climate Control; ?? If so then the cable working the right side is either broken or not connected . If it is a USA version and has Auto Climate Control then try going to defrost and see if you get any heat on both sides ;also it is rare but could be a partially restricted heater core to that side .

It is an American version with auto climate control. Only one button is working on the climate controll, the one closest to the driver. Is there a way to cange it to defrost manually?

Thank You for the help.

Well that paticular button is the Defrost on your model ;did this problem start all of a sudden or what is the history if you can give a little more info like did the system ever work since you got it??? The Auto Climate Control on your Model has a series of relays and vacuum switches that control where and what air is delivered to which vents .It may be that you have a vac hose disconnected under the hood that suplies vacuum to the system or possibly the push button assy itself is defective .Try pushing the two buttons directly next to the one that works at the same time and see what gives .

You have too many ducks on this June Bug with posting the same prob in diff places so you need to get it all together so we won't be answering the same q's in diff places chasing this thread to death . Good Luck to you.

I ment to move this post to the diesel discussion.
 

Yes I need to post in one area only.

I thought it was more appropriate for the diesel discussion.
I moved it there and forgot to stop this one.

I'm a newbie to this board. :o

Plus we are starting on a long trip for the holidays tonight.
And I'm already a little frazzled.

My apologies. And thanks.
