Low coolant? Wrong thermostat temperature range? Heater core plugged,restricted or airbound? Water pump not circulating coolant? Temperature control cable not adjusted properly?
you must be a wierdo.stupid.
I have a 2000 zx2 and it has a thermostat, if that is your question. Having said that, my heater quit working and it turned out to be the cable came loose under the dash on the left side of the radio. At first I thought it was the thermostat but was wrong. Duct taped the cable in place and the control and heater started working fine again.
When my heater didn't work i had to replace my thermostat.
Try taking the car in for a rad flush. You may have a restriction. Check also that the hoses are not kinked, block heater and rad.
Probably your thermostat
Wrong thermostat? Wrong installation procedure?
could be thermostat or heater fan if you can hear all the speeds on the blower motor working then it could be your thermostat but your heater core might be plugged as well
check your thermostat or your heater core may be getting ready to go out
Usually a thermostat will fix it, could be low coolant, heater control, wrong thermostat (should be a 195 degree) or restriction in the heater core or cooling system also.
I would guess the thermostat I would guess the thermostat
air block in heater hose most likely bleed it
if the blower motor works most likely heater core is bad. need more info
You probably have a bad thermostat.
Check the heating elements in the water heater. These may be bad and need replaced.
You may be low on coolant, or the thermostat is stuck open, or the heater core is plugged up, or the temp blend door is broken.
the heater core could be stopped up, or could be low of antifreeze, or the thermostat could be stuck open
Thermostat stuck open, clogged heater core, heater flow valve not functioning, or low of coolant.
If a hot tub is not holding temperature there could be several things wrong. The heater function has stopped working or the thermostat is faulty. Also check to make sure the heater has sufficient fuel. The thermo coupler on the water heater may be faulty.
try the bend door
Depends on what is wrong with it. Can be a bad thermostat, or a broken or loose wire. Can also be the element is broken.
I would expect a plugged heater core.Take your hand and feel the two heater hoses that pass thru the firewall on the passenger side; if one is hot and the other is much cooler, than you heater core is plugged and needs replacement.
All I can think of is you got a defective or the wrong thermostat, because as far as I know the only thing that regulates the temp is the thermostat. Also if anything else in the coolant system was bad you would usually have a over heating problem. Have you tried touching the heater core hoses, If the heater core is cloged usually only one hose will be hot because the core is plugged and not lettig coolant flow thru in and out. Do you have a heater control vave that could be stuck?
check your thermostat it is most likely stuck closed also drain and flush your cooling system
most likely thermostat stuck less than $ 15 part
