Do you think taking it to the dealer for evaluation makes sense?
Thanks

I'm thinking the reason for the thermal fuse failure is the cabin air filter being dirty enough to cause the automatic temperature module to work too hard to move an appropriate amount of air thru the system, overheating the thermal module.

I sound like I know what I'm talking about, but this is just an educated guess. It would be nice to know if folks who have this failure have a "very" dirty cabin air filter, or if it has not been changed in a long time.

I've got an '04, and have not experienced this issue before. I have been paying the dealer unreasonable amounts of money to maintain this vehicle however.

Front blower stopped working. Reordered same part that fixed the rear blower from Digikey (P10920-ND $0.74 THERMAL CUTOFF) and $3.08 later the front blower was up and running. The rear blower filter was covered with lint when the last resistor went bad. The front blower stopped working just after I replaced the cabin air filter. It will be interesting to note how long the repair lasts. I really should start ordering a few of those resistors at a time and remember where I put them. Still beats paying $70 for the replacement part and $50 for the blower motor.

Anyone in LA/SFV area can help me with this issue?
I never soldering anything in my life and it's probably too late to start learning

Have an 02 MDX that stopped blowing air out of the front vents, whenever I try the front it instead goes out the back vents. I was quoted about 1k for repairs so instead I'm going to try and fix it myself with the info everyone has provided above and hope for the best.

Sidewinder, you are the best! Nothing was coming out of my front vents and this was the first thread I came across when researching it. I bought the 75 cent thermal fuse online as suggested in the thread and installed it in about 5 minutes. Everything works like new again. Thanks again sidewinder and thanks to the forum.

First I want to Thank, each & Everyone of You for putting This Together with the related Posts !
NO A/C, Died when The Temp, was 104. With all The Computers, I Thought I was done for ealer "Please drop Your Full wallet, Here".
After bremoving the Transistor Assembly, We used an Ohm Meter to check The Fuse, FIRST. NO PROBLEM. Frustrated, We decided to start a Process of Elimination. End Product First. Pulled The Blower & VIOLA ! Problem Found. 2 lead wires to your Battery, ( W/ Alligator Clips ) And You can test the blower with Your car Battery. ( There is A Positive Tab & a Negative Tab ). An order at Advance Auto, We got a Replacement over Night, for 91.00. 45 minits later, WE HAVE HEAT, DEFROST & AIR ! Thanks Guys !
