SOURCE: Why doesn't the heater blow hot air?

If your "Check Engine" or "Service Engine Soon" light is on, you need to have that checked out first.
If not, the next thing you should check is your engine coolant level. (Antifreeze) If the coolant level is low, the engine coolant does not circulate through the heater core and the the heater doesn't work. The coolant level could be low for a number of reasons including a leaky hose, water pump, or head gasket. In any case, if it is found to be low, you need to find out why.
If the coolant level is OK then the thermostat function needs to be checked to make sure that the engine is reaching operating temperature.
If all of the above checks out OK, then the heater control valve and/or the blend air door in the HVAC housing needs to be checked for proper operation. (NOTE: some cars are not equipped with a heater control valve)

SOURCE: my heater stoped blowing hot air.antifreeze level

If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox and Pontiac Torrent,

Where is the flasher relay located on an 83 subaru gl wagon?

try looking at the fuse box, or a distribution box of fuses and modules in the engine compartment, or, actually if there is a dashboard glove it and try and look behind in there.

Fixing automatic. Choke on a 1985 subaru gl wagon

What fails on these predominatley within the choke system is the vacuum dashpot/pulloff.This slightly opens the choke plate with vaccum present after the engine has started and gives the engine some air.The engine will be under a very rich condition without this opening.Unfortunatley this pulloff is incorporated in the carburetor top which will nesessitate replacement of the carb top portion
