I just purchased a 2003 Discovery SE7 and am having a hard time figuring out the AC/Heater. We have been having 30 degree mornings. The vehicle is equipped with rear air, but it is always cool...never warm. If I turn the rear blower on, it freezes my kids. The only way I can warm the rear of the vehicle is to turn the temp to HI and the blower to HI and sweat it out until the rear thaws out. Then, when I crank it down, the back gets to cold. Any suggestions/help will be greatly appreciated.

Best regards,

Eric

 

There is no rear heater as part of the rear a/c system, Sorry.

Not sure if the 2003 is the same as 2000, but if so,make sure that your climate control is on economy. This disables the A/C compressor.

 

x2 on the econ button i have an 03 and it does heat up a lot faster without the a/c compessor running. and turn on the heated windshield to defrost the windshield. plus as soon as it starts to get warm turn on the recycle button.
