Hi. I hope someone can help me. My 2012 KW T800 daycab is giving me a headache. I cant get the blower to stay on. Had the heater core valve replaced a week ago because it was blowing hot air all the time. Now the fan wont stay on. Any suggestions and is this still under warranty. 127000 miles on the truck. KW made me pay for the heater core valve.
Thanks
