Sounds like your thermostat is stuck open or your heater core is clogged. Does the temp gauge go up to about 200°F? If not it's the thermostat. HTH. -Jim

It's the thermostat. Once you replace it the temp gauge will go up to where it should. The gauge isn't moving because the engine can't warm up because the thermostat is stuck open. HTH. -Jim

Hello Jim, sorry to bother you again but before I ask about other issue I would like to thank you so much for your help. I took your advice and change my Heater Core and that's exactly the problem the old core was old and clogged up now I have too much heat!!! it's great!. The issue I have now is my heater is constantly blowing heat even if I slide the lever to the left (Cold) its still blowing heat. The lever now is not fully slide all the way to the Heat section it stucks half way on the heat section. Where can I actually locate this problem? Thanks. Vic

Hi Vic, glad you have heat! Sounds like the cable that controls the temp door is out of adjustment. The cable runs from the back of the heat/Air Conditioning control panel to a lever on the heater box under the dash. Make sure it's not pinched or binding. If that is ok check for an adjustment turnbuckle. Was it like that before the heater core replacement? If not, just retrace your steps. Maybe the cable got misrouted during reassembly. HTH. -Jim
