Hello I am a new member and I recently bought my 94 explorer. She ran fantastic last spring when I bought her but now here in this quite cold Oregon winter I can't get her to heat up! The gauge barley hits the NORMAL position so there's little to no heat in the cab. Should I try a hotter thermostat? Perhaps thermostat stuck open, or should I try a bra over the radiator? Any suggestions would be greatly appreciated!
