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.

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.
