P0495 Fan Speed High code
My 2006 Trailblazer is showing the P0495 Fan Speed High code. The light came on while towing a VERY heavy trailer up a steep incline in moderate heat. The guy at Autozone who read the code said their computer suggests a thermostat repair, but I suspect that it could have been high due to the load and the heat. Could this be the case? The fan sounds normal to me now, it's cycling on an off at a relatively normal interval.
