You know I have to take pics every time I pull apart the Pilot....
The power transistor for the rear blower in my 2003 stopped working the other day.
Thanks to Slayder, Sunday Rider, N_Jay, and many others who have posted on this problem.
Here is what I did to fix it.
I ordered the parts from Mouser Electronics. I got 2 of the thermal links and some thermal paste:
1 526-NTE303 1 1.770 1.77
1g HEATSINK COMPOUND
2 447-XYP2BN109-RC 2 0.400 0.80
Xicon Thermal Cutoff
TCO 114C 2A/250VAC
The total was $9.02 shipped.
1. Pull off the panel on the left side of the main console in the drivers footwell.
Here is a picture of the intake screen for the rear blower. You can see how clean I keep it, but the part still failed.
13. All that's left is to snap the hood back on by placing the pins into the connector end and the latch through the heatsink. Replace the part in the Pilot and test... Replace kickpanel, etc...
I have a 2004 Pilot EX-L with 72000 miles and 3 months out of extended warranty...rear blower went out about a month ago, then front blower went out 2 weeks later, right when we had our first freeze in Dallas area...since we had no heat and 2 little kids, I purchased the front BWD branded resistor assembly locally at O-Reilly auto parts for $103 and it works great. Now on to the rear resistor...since it is not as urgent, I will give the listed fix a try. Just ordered following parts from Digikey.com:
The recommended one:
P10921-ND EYP-2BN110 THERMAL CUTOFF 115C 2A/250VAC $0.74
The one I will try first due to higher temp allowance:
P10925-ND EYP-2BN143 THERMAL CUTOFF 145C 2A/250VAC $0.74
Thanks for everyone's input.
Wish me luck.
We're still running the jumper in two separate Pilots now. No issue for a year and a half. 110*f Vegas summers and 9*f Reno winters.
I have tried both replacing the thermal cutoff, and using a jumper wire and I am still having the same problem where the rear blower is on High, no matter the setting up front (or if the AC is turned off).
I have the transistor assembly that looks like the 2nd picture you previously posted (does not have the "tabs" sticking up). Any ideas on why it's stuck on high?
Our 2006 Pilot recently lost rear AC too. I pulled the transistor assembly out and tested it. The TCO was blown. A new assembly fixed it good as new... and of course, the obligatory vacuuming of the fan screen.
My assembly is also the newer version. I am considering repairing my old unit so that I have a spare in stock. Has anyone repaired the newer version yet? I haven't taken it apart yet, other than to remove the brown cover.
Also, I tried to find a 2003-2008 Pilot in a junkyard and snag the transistor assembly, but in my area, the junkyards are charging a $50 minimum and wanted $65 for the part. My dealer pricematched my online prices and I got a new part for under $90 with tax.
Yes, if I decide to not repair it.
Have you repaired the newer version?
