Well, I bought my 2000 GS 300 this summer and was always using AC. Now that it's getting cold, I've been using the heater. The left side/drivers side blows out heat just fine, but the right side/passenger side is always blowing out cold air. And yes, I have checked the dual button. Both sides I change the temperature heat to 80, and only my side is blowing heat.

I don't know if this is an existing problem from when I bought the car, or if possibly something could have been messed up when I got a new stereo installed.

Can anyone out there help me out or give me any ideas?

Thanks in advance.

Similar thing is happening to me. Now that is getting warmer I am using the AC. The driver’s side comes out cold but the passenger side comes out warm.

Any help will be appreciated. I will continue to search for help.

 

i have the same exact problem....
AC is on, "dual" is turned off....temp is set at 65.....drivers side is cold....but passenger side is NOT cold (but its not blowing heat either)

any help would be greatly appreciated

 

PR - any update on the solution to this issue? i am having the same problem as you. any help would be greatly appreciated. thanks.

 

No.. I am still researching on my free time. so far I have no solution. I have not tried anything yet.

I guess one of the cheapest posible fix I will do first is to recharge the freon. Ill do it myself it should not cost more than 40 bucks.

Ill keep you updated. Ill prob. do it on the weekend.

 

PR - the DIY ac recharge worked great for me
