Okay everyone, after 139,000 miles I believe my rear power transistor has finally given up. I have reviewed previous threads and have removed said transistor and tried checking the resistance. It reads 1.5 on the 200K ohm scale. Unfortunately I am not exactly sure what that means if it is good or bad. I found a scan from the shop manual that describes an alternate way to test the front transistor by applying voltage through the connector. If possible could someone please post the procedure for doing the same through the rear power transistor.
Of course this happens the week of the family vacation to the outer banks, where A/C is of some importance! :D
Thanks for your help! |

That sounds like 1500 ohms to me. Not the virtual open circuit the TSB is looking for in order to condemn the module. That takes you to the "NO" branch:
"NO —This service bulletin does not apply. Test the blower motor system for other possible causes (see page 21-94 in the 2003–04 Pilot Service Manual)."
I would double check it again before you go on a wild goose chase. Make sure you're measuring across the correct terminals. |

Problem Fixed
Replaced the thermal thingy with the model from Radio Shack and all is well in the land of milk and honey, and A/C. Probaly going to go ahead and order the actual replacement unit though for peace of mind.
Thanks to all of you! |

I did mine a year ago, and it still going strong. I think the cost of the unit will surprise you! I have an extra thermal sitting around just in case.
Did you get the ceramic one or the metal one? The radio shack near me only had the metal ones, and I was affraid of it grounding.
Good work. |

RadioShack has thermal fuses? |

I got the metal one and did have a short issue at first. I realize the cost of a replacement piece is rather high, however I also look at my $2 investment in the Radio Shack fuse as replacement for the shop time to diagnose. I am just a little leary about being out on the road and something happening.
Radio shack has them item #270-1322, they were in with the regular fuses at my Radio Shack. |

I did not know they had any.
I'm a little Leary since they don't have any current carrying specifications.
Is there any written on the package? |

Silly me.
I looked under "Tech Specs";) |
