drumkendrum Posted July 19, 2018 Share Posted July 19, 2018 My 98 impreza L wagon heat cuts off when I have it blowing full blast, when I turn the nob to turn it off and then on again it comes back on. But after a little while it will shut back off. Anyone have any tips on what I can do? Thanks! Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted July 19, 2018 Share Posted July 19, 2018 the fan cuts off? or, does the fan continue blowing but the temperature is not hot? (why the heater in July ?) 1 1 Link to comment Share on other sites More sharing options...

(why the heater in July ?) I am trying to fix it if I can for the fall/winter coming up lol. The fan just cuts out all together after a time and wont blow, like goes silent all together. But if I turn it off and then back on it comes back on for a time. Link to comment Share on other sites More sharing options...
lmdew Posted July 19, 2018 Share Posted July 19, 2018 There is a resistor pack in the air box ducting below the passenger glove box. It's most likely going open, no voltage to the fan. Then the circuit closes providing power again. Easy change 2 screws and a plug. Link to comment Share on other sites More sharing options...

I know where it’s at, I’ve actually taken the fan apart before to clean the unit out to see if it helped . Link to comment Share on other sites More sharing options...
lmdew Posted July 20, 2018 Share Posted July 20, 2018 The resistor pack is about an 1" square and about 2" long. There is a electrical connector and 2 screws that you will see on the air ducting under the glove box. Remove the connector and the screws pull it out. Put the new one in. The link shows a nice picture on amazon. https://www.amazon.com/Wells-JA1230-Blower-Motor-Resistor/dp/B000EQO07O/ref=sr_1_3?ie=UTF8&qid=1532083883&sr=8-3&keywords=Subaru+Impreza+fan+resistor Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 20, 2018 Share Posted July 20, 2018 High speed doesn't use the resistors. Probably either a failing blower motor or a relay that can't stay pulled in. GD 1 Link to comment Share on other sites More sharing options...
lmdew Posted July 21, 2018 Share Posted July 21, 2018 Yep, I missed he was on High Speed. I have some spare fans. $20 shipped Link to comment Share on other sites More sharing options...
