Mike Donohue Posted February 26, 2019 Share Posted February 26, 2019 If I start the truck (Cold or warm) the heat will not work, sometimes the temp gauge goes up enough to kick the fan on although the air is cold blowing thru. Odd thing is , once you go a few hundred yards all is good. Is the thermostat sticking? Why would it suddenly open from moving a short distance? 1999 CH613 Quote Link to comment Share on other sites More sharing options...
