My ford explorer only blows heat when turned all the way up

Sway bars are there to give cornering stability when steering and as such is a safety requirement. The link will be cheap and easy to replace so why waste time and risk safety to put it off. As to the heating problem and I would be checking the control module that allows the heater tap to turn on as it appears that there is insufficient coolant getting into the heater either from a tap half on or blocked hoses/core.

2002 traurs no heat both heater hoses hot blend door seems to work new thermostat

i just went through this in my 2001 F250. first check to see if you have flow switch in your heater hoses. this opens and closes to let hot water in your heater core. mine did not have this, but here is what my problem was. i had used that pink antifreeze. it slimmed up in the heater core. i blew air through the core and un plugged it and had heat. it was hard to get that stuff out as i flushed the system 2 times and put in green antifreeze. in desperation the 3rd time i blew air through and got it clean and that was the end of my heat problem.

1997 sl2 inside heater barely heats

What temp thermostat did U put in????? Check and see what thw manufacture call for you car. Also check to see if any leaves are in your heater box, which is stopping the air flow. Some cars have and air filter on the inlet duct. It could be plugged. Check this out also.
Take the 2-heater hose off where the water goes into the heater coil. Back flush it with your home water hose, the oopposive direction that it normal goes. It can get stop-up. You can also flush your whole system by empting the radiator and put a can of old time comet into the radiator, and fill it also with water, let it run for 1-hour, the empty a,d fill with water 2 more times. Fill it back with antifreeze and go with it. This should clean everthing.

Heat lack of

9 times out of 10 on this old of vehicle its the heater core. If your car temp gauge is working and the car is heating up fine and the blower works then it is most likely your heater core. Not sure how hard it is on that car. SOme times it just under the dash takes about 30 mins but some cars you have to pull the dash out. The part alone is cheap. I would try logging onto put in your car find the part (heater core) then look at the how to change section of auto zone.
