Moved from a '97 land cruiser to a 2000.

The vents above the second row seats blows cold air, but I can't seem to get them to blow hot air.

Do they really not work with the heater in the car, or am I missing something?

Thanks,

Phil
 
Rear Heat was an Option and its components are mounted under the driver seat and rear for the center consul. I don't have it either and kind of wish I did.

Has anyone added it to their truck? If so please give us some details.
 
Rear heat is delivered by vents at the rear of the center console, and only when the "Rear" fan button on the HVAC control is on. As Onpoint01 said, the rear AC [if fitted] feeds the roof liner vents only.

Thanks for the diagram. Learn something new everyday. I guess they really do mean "REAR AC" and not Rear HVAC :)
 
What makes it more confusing is the blue/red band with 85F at one end. You'd think that means 'hot'.
 
Yes the indication of warmth via the red band on the temp selector does give you the indication heat exists. Does the rear AC have any air mixing capabilities?
 
No mixing door. Just pulls ambient from PS rear and blows overhead. I'm guessing the temp selector throttles the response of the expansion valve as perceived by the overhead temp sensor.

AFAIK rear heat was standard on all 100's, I'd be surprised to see one that doesn't have it (and if a '00+ model still does have rear AC). Unless it was removed at some point.

There's no vent mix between the upper and lower vents, so if you have the upper controls set to heat, all you'd be doing is recirculating the warm air the lower heat vents are putting out.

No rear heat on my 01' and I know it wasn't removed.
 
You don't have the blower motor under the driver's seat and the vents at the bottom of the center console? What about the plastic heater tee's at the firewall?
 
I think rear heat was standard on all LC's from the 40 series on up... no? ... and it has always come from the floor. Makes sense as heat rises and cold air falls down.

Picture of center dash console?
 
I agree with Hoser. If it was standard on a 67 LC it should be on a 2000. Especially one that has AC in the rear.

By that standard, we should have SFA and Manual Trans.

I do have vents at the bottom of the center console but no controls. I do get rear heat but not via a blower motor and extra heater core under the drivers seat.
 
According to the 2001 sale brochure rear controls were optional with the 'third seat package'.

My heat is supplied from the front vent system from what I can see. See the attached picture of Rear Heat Control which I do not have.

Do you have a rear heat control (off-on switch) below the radio??
