Hi all,
I had a strange problem last night that mysteriously disappeared and has me wondering why it happened. I was driving along and suddenly a Contact Dealer message comes up, the coolant temperature gauge goes to dead cold and the hvac defaults to defrost. I restarted and went into engineering mode just to see what the coolant temperature was and it read 0C. As far as the hvac goes, I could change mode position on the screen but it stayed in defrost, temperature worked fine as I was able to get plenty of heat. The car ran fine but had that message. After a few hours it just went away. Is that message related only to body (bcm) functions. Once that went out a few miles later I got an SES for coolant temp being to low and an insufficient switching on b1s1. Any ideas?
Thanks
Tom
