Had just come off freeway and parked. Noticed that climate control was blowing hot air (excessively). Turning the control to cooler settings just increased the blast of heat. The dual setting was not working either as most air was being forced to the driver side. The strange thing was that shortly after that, the parking brake service light came on!.after stopping and turning the ignition off and on a couple of times and engaging and disengaging the parking brake a couple of times also, the parking brake service light has turned off. It came back on once or twice, repeated the steps, and 'so far' has not come back on. But the heating/cooling, or lack of cooling is still a problem even through all controls seem to be operating properly, including the passenger side temp control is operational but does nothing as far as heating and cooling. At first it seemed coincidental for both the climate issues and the parking brake issues to occur at the same time. But after a search of the web turned up other people reporting similar 'coincidences' of the same combination of problems and then finding two complains on this site that also report the same basic information, I no longer believe that they are coincidental but may in fact related. In both complaints, 10305448 and 14499467, they talk of the braking brake service light and or issues with the brake actually engaging with one also mentioning the blasting of only heat out of the ducts. I find it very interesting and possibly worthy of notice as the dealers in both complaints relate the cause to interferences between the components, the parking brake electronics and the dual coolant control valve.

It was driving fine one day until I went to start it. It said etc engine fail safe mode, check parking brake and something about the gears. It starts sometimes, I've had it shut down while doing 50 mph and lose steering and bad braking. This is a potential hazard for my newborn in the car. Now it wont start and no one knows what the problem is. How can they sell a car that they cant find out the problem on themselves and sell it?

As soon as the warranty expired the vehicle began to have intermittent error messages about the parking brake needing service and the climate control began to blow only hot air. Vehicle has very low miles, garaged meticulously, serviced. Lincoln contacted about the issue and was told I needed to have dealer run diagnostics and then they could know whether they may be able to help with repairs to climate control. Paid $170 for diagnostics, dealer and Lincoln refused to do anything sticking me with the bill. They made the excuse that it was my fault because it may have occurred because I didn't drive it enough. I was shocked, its first time that I've heard suggested that taking care of something caused it to break!. ridiculously poor customer satisfaction department.
