bought a 07.5 about 5 months back with very low miles. Tried the seat heaters about a month ago and no blinking light, no heat, nothing. Checked fuse and connections all OK. It is a six speed and there is a single high / low switch on both sides of th shifter. Any ideals?

 

Not sure if it applies to your situation but the heater wires are super thin and like to brake and burn up. I just re-upholstered some seats and found the driver side to be toasted. Could be that or double check that all of the connections are solid, could have pulled something loose putting something under the seat?

Good luck
