2005 silver
Hello. 2005 XLR purchased in 2008. 50,000 miles. Always in a garage and tender. The A/C on the driver's side is 20 degrees warmer than the passenger side. Heat seems fine, just the A/C
puts out around 75 degrees on driver's side but 55 degrees on the passenger side
Maybe passenger side sensor? Just a guess but try everything else before considering replacing the heater box. I think they started the assembly line with the heater box and built the car around it.
Thanks. The passenger side air and heat is fine. The driver's side heat is fine but air is too hot. I wonder where the sensor's are located. I am looking at getting a service manual and wrestling with a hard copy or a much cheaper USB version. Any idea where I can find these sensor locations online?
Drivers side sensor is just below the start button.
System uses a foil roll with holes in it that wined back and forth till the proper patch with the holes for the selected function are aligned.
Okay will check that out. A thermistor that "opens" will show high resistance which relates to lower indicated temperature (than actual). Perhaps that is keeping the blend door partially open, passing heat.
