SOURCE: heater and airconditioner work half time thermometer varies

It could be the thermostat (simple fix), check this first, Then i would go for the water pump but worst scenario would be the head gasket gone, Have a pressure test done on the car to eliminate this, Hope this helps

Mine use to work on high only. It was the switch cylinders, something like that. It was an easy fix. Now my blower motor works intermittently. If I kick it, it turns back on. It is located on the passenger side close to the door side directly above your feet (below the jockey box). Kick straight up. If you need to replace it it is also an easy do-it-yourself repair. Make sure before you go out and replace your blower motor that you check your switch. A lot of repair shops will replace the motor w/o checking the switch, you end up paying for 2 repairs. You can make sure it's not the switch by jumping (bypassing) the switch.You apply jumper wires (not cables) directly to the motor, if the motor turns on you know it's the switch.

SOURCE: need to know how to change a thermostat on a 1990

Doesn't sound good. Usually t-stat is on engine. Follow top radiator hose to engine should be located there behind a 2 inch dome attached by two bolts and radiator hose is attached to the dome.

Now subaru's can't handle overheating. Slightly hot as in got to red but shut off imediatly, will often blow the head gaskets. Got hotter than that will crack the heads. as in drove more than 2 miles near red mark on guage. or by adding water while hot also will crack them.

Broken fan belt? was it timing belt and bad water pump? if water pump age is unknown will need one of those too. and most likely timing belt and some pulleys.

Good news is you can't hit the valves with a broken timing belt on these cars. But the timing marks are confusing there are 5 or so on the center gear but you only use the one on the back of the pulley on a tab that is a straight line. Point it up at the mark as book shows. the other two marks are ok. Putting in the belt tensioner is testy so good luck.

Best price for all these parts are on E-bay You can save hundreds by buy the sets.

1987 subaru 1.8 station wagon heater puts out little to no heat,have put new thermostat in and still no heat

Since it is a 87, you probably need to replace the heater core. If the heat comes up with the higher RPM's of the egnine, maybe a water pump.

No heat while idling

I have had a similar situation myself and it was my heater core, on my vehicle it was a very time consuming job as i had to remove the entire dash to get to it. What you could try first if not tooo bad . Flush the system and reverse the hoses on the heater core and reverse flush. You can drive reversed for short time with the heater core hoses reversed as i did for over a week it may un plug if not as bad as mine was....Plenty of how tos on u tube to reverse flush your heater core and system.. I replaced my heater core radiator and water pump and a vent was broken in the dash i found and bad vacuum lines. a couple actuators were bad. had no heat to floor after doing all that it roasts me out of the truck, and the vents work properly including blowing on my feet the way i prefer.... Hopefully this helps you

My 92 for taurus wagon is blowing cold air instead of hot air, what could be the problem?

Behind the tempearture switch is an arm that is telescopic and raises and lowers the temperature. If this arm is either broken off or loose, it can create an inability to change the temperature. It can also be a problem with the heating unit in the ac in the car.

If your low on antifreeze the heater core may not be getting sufficient coolant. Heater core most likely clogged if you're not low on antifreeze

The heater does not work there is no thermostat in right now and I also have a temperature gage that flux and what she wakes up and down it's normal when moving and go as high or when idling

The thermostat is used for the heating system. It slows the antifreeze down in your radiator to allow it to warm up before its cycled through your heater core. Put the thermostat back in, heater will work. Will also regulate flux temps.
