Found another thing that needs fixed yesterday, no heat in my Suburban. Changed out the blower last week, had fan and heat then. Temp gauge acting normal so not going to jump on thermostat, will check coolant tho. One hint I have is that the cold/heat slider doesn't feel right, think it's a mechanical control to either a flap or possibly a water valve, can't remember. Time for a look and maybe even my Haynes manual!
