My nephew's 98 was doing that. He tried changing the thermostat. No difference. A mechanic unhooked his heater core lines and flushed a bunch of junk out of it and it worked great. That was 2 years ago and his heater is starting to get lame again. My '97 is also not blowing the greatest heat. I'm going to try the thermostat change and heater core flush and see what happens.
by fire . an electric heater is a metal, and a metal is a good conductor of heat. so it can produce heat
A possible cause could be that you have a clogged heater core.
Yes, replacing the heater core should slove the problem.
Its power source is not turned on or it requires repairing.
NO! THE HEATER CORE IS YOUR CARS HEAT SOURCE YOU CAN BYPASS BUT IS NOT A GOOD IDEAL IN WINTER!
There are a few potential problems possible. Plugged heater core, collapsed water lines to or from the heater core, low radiator coolant, engine thermostat stuck open, or a faulty damper in the heater ducting.
Its your Heater core if it smells like a syrupy sweet smell if not then its your thermostat
Sorry bad news Your heater core has a leak
It will give heat to about 13 feet away. This outdoor item will give heat as soon as it is turned on.
First make sure you have coolant in your radiator.Pull off heater core hoses and connect a garden house to the pipe and flush it out.Check vacuum lines by the heater core hose.
Have you used any stop leak in rad.? If you have pull off heater hoses and back flush heater core. Also check hot water control valve for heater.
The coolant is low, probably from a leak. You need to have it checked with a pressure testor.
