So I replaced the thermostat and things seemed to be good.....Went to work this morning and the same thing happened again, normal,(LOTS), or heat in the cab but the dash temp guage reading nothing. After about 1/2 hr at work started the truck up and the temp guage was reading fine????? This only seems to happen when its cold out? So where is the temp sensor located? I am wondering if the electrical conection could be loose? Any help would be appreciated.
BTW Merry Chrismas all.
