SOURCE: heater doesn't work

Sounds like the heater core is stopped up. Try removing the heater hoses and backflushing the core.If this doesn't work replace the core.

sometimes the radiator is just too plugged to respond to flushing. (happens a lot with a marginal radiator because when flushing, the solvent simply goes around the plugged area, and cannot build up enough force to break it free). From what you have written, this may be the case. Is the electric fan coming on and off at the right times? if not this also can give you similar problems. You have done the right things but may not have gotten the desired result. Hope this info helps you a bit.
good luck

What causes hyundai Elantra 2002 tempature gauge fluctuates between normal and hot


The thermostat "seals" the cool coolant giving up (rejecting) heat in the radiator & heater core from the hot coolant absorbing heat in the running engine "block".

When the coolant in the engine reaches a specific temperature (180 ~ 195 degrees) as determined by the value selected by manufacturer or when replaced, it opens and allows the hot coolant in the engine block to be pumped out to the radiatot & heater core for cooling and the cool coolant in the radiator / heater core is pumped into the engine block - replacing the hot coolant. The thermostat senses cool coolant in the engine block and seals shut until the temperature of the coolant in the engine block rises to 180 ~ 195 degrees again. This process continues over and over for as long as needed.

You should check to make sure that the coolant level in the reservoir / radiator is sufficient by checking when cold. Do NOT remove a radiator cap when it is hot! With the cap off, start the engine and add additional coolant as the engine warms up to normal operating temperature. If coolant levels are ok, the trouble could be related to the thermostat or possibly a faulty temperature sending switch. This means that the temperature of the coolant is fine - but the switch or sensor that converts the temperature to a voltage for the gauge on yur dashboard is the problem.

If the temperature is fluctuating up and down, you should have it fixed. Good luck!

My 2001 mercury sable runs hot (temperature gauge goes high then drops back at half also


Check your coolant level visually by removing the radiator cap (only when it is cold). Also make sure the coolant temperature sensor for the cooling fan is functioning properly. These are set to operate the fan when the engine coolant reaches a predetermined temperature. These go bad in time and need replacing. Sounds as though yours may be working intermittently.

97 Mercury Sable, overheating but not on gauge, now won't stay running


Check the thermostat. The temperature sender is to the right of the thermostat and if the thermostat doesn't open the hot coolant from the block won't be flowing to the sender/gauge showing it is overheating. The thermostat is at the end of the top radiator hose where it enters the engine. Check the wires to the sender to make sure they are connected. Flush the coolant and heater core at the firewall connections as it may become clogged.

Temperature gauge fluctuates


First of all you have a bad heater core that needs to be replaced. Second you may have a bad temperature sensor. Make sure the radiator if full of water

I have a 2002 Mercury Sable 3.0. I noticed when


The clicking noise is the motor for the "blend door". The heater core and the air conditioning side share the same ducting. When you move the knob a small motor moves the door letting the respective hot or cool flow happen.
The heater core is probably blocked. The engineers at Ford have the coolant hoses bypassing the core with a WYE at the firewall. The coolant takes the path of least resistance and stops FLUSHING the heater core and it eventually clogs.

Fluctuating engine temp a/c sends out cold air intermittently


Here's the thing. The ECU will shut down AC if the engine temperature is too hot. If the coolant temperature sensor is malfunctioning (lying to the ECU) telling it that the temperature is hotter than it actually is, the computer will turn the AC OFF.

My car heater is blowing cold air


The shut off valve on the heater core was left shut during the repair on your coolant system. the repairman forgot to re open the shut off valve . this is the problem. open the shut off valve and, the air will become hot again. as for the gauge fluctuations, the actual gauge may be malfunctioning.
