Question about 1993 Lincoln Town Car
Hello and thank you for your knowledge. I'm leaning towards the cabin air temp sensor. Where is that exactly? I've replaced the blend door actuator. This problem is so intermittent-it's crazy! For over a year the Auto feature hasn't worked. Today, if I first 'reset' the blower switch low to high the Auto feature will work. Over the last couple of weeks, the Floor position of the HVAC controller has worked, but didn't when I bought the car over a year ago. I know exactly what it is to R&R the dash to replace the bda and the heater core. I'm leaning towards spending the money that it would cost to replace the HVAC controller and sensors on rebuilding my engine in my 88 Signature Series where just about everything works perfectly. I love the better ride of the newer ones, but I do not love their continual electronic headaches or the fact that to replace the valve stem seals, I have to shell out over a grand! What I could do with a grand on the 88!

This could be a cabin air temperature sensor. It could also be a failing air door actuator. If the interior temperature reading on the climate control panel seems to be accurate, the air door actuator is the more likely culprit. It is a small electric stepper motor which is more prone to wear than other components of the A/C system. The A/C control computer can also be at fault, but if it appears to read temperature accurately and doesn't flicker or show an error message, it is probably OK.
