I tried to put high speed fan but it still getting low fan. cause blower motor speed control resistor or air blower motor fan? anyone get idea?

 

most likely the switch itself.

 

Anyone idea? i have no clue what going on.

 

ac power transistor

 

ac power transistor??? what is that

 

where i can find of power transistor???

 

sorry but picture will not load.

You need to replace this piece. I am not sure what it called formally but, I had the same problem where I was only getting one setting – LOW – once I replaced this part I got all four settings… I have this one as a back up, if interested let me know.. here henryd42501...yahoo.. email me here I will get you a picture.. please state need picture on subject.. I will delete email if seems suspicious...

 

To load a picture, upload the picture on imageshack.us or some image hosting site like that and then post the link.

I actually want an answer to this too. Even though this thread is 2 years old

 

yes, if your A/C only blows on the low setting, you need to replace the A/C power transistor. it sits under the glove box.

 

Good looks kleres

 

thanks FutureSc got it... here is the pic. anyway.. http://imageshack.us/photo/my-images/228/imag0175i.jpg/

 

do you have a pic of the other side, or the numbers on the actual power transistor case?

 

Part number on the transistor: 077800-0191

The backside looks fits up into the AC system and just acts as a block off plate.

Thanks. Does anyone have a dead one around? I'm thinking I could take it apart and what we will find is a $6 power transistor, a bias resistor, and a thermal fuse ($4), or a total of about $11 in parts.
