problem with heat
 

heat stopped working all together was wondering where the thermostat is located on the svx any info/ pics of its location would help thanks

Re: problem with heat
 

The thermostat is located on the front of the water pump where the lower rad hose goes into the engine. There are two 10mm bolts holding the t-stat cover on. Drain the rad first, remove the lower hose, remove the t-stat cover, remove old t-stat, install new one with new gasket, replace cover and hose, fill and bleed coolant.

If you are getting no heat whatsoever, its much more likely theres a problem with the mix door or control system, or you are very low on coolant, OR your water-pump is toast.

A stuck open thermostat will still allow the engine to get warm enough for heat.

And what does your temp. gauge read?

Re: problem with heat
 

ill have the engine all warmed up and i have the temp set to 85 but its nothing but cold air

Re: problem with heat
 

If the temp. gauge reads normal when driving the car, then look at the air mix door as Socal mentioned.

wheres the air mix door

Re: problem with heat
 

Under the passenger's side dash next to the center console. Rectangular box with 2 white nylon rods connected to it. They operate the air mix doors but the nylon gear that pushes and pulls them can get fouled with dirt or be stripped. First check if you are getting power to it. It's a pain to change but can be done without removing the glovebox or dash. Fortunately mine worked again with a good cleaning.

any pics of this area?

Re: problem with heat
 

Don't have any pictures but here is the parts diagram from Subaruparts.com.
The mix motor is #2 on the bottom of the heater box. The mix door rods are #7 and #8. You might try giving them a nudge while raising and lowering the temperature and see if they will start working again. Also a power test to the electrical plug to see if a signal is coming from the AC control unit.
