Blower motor connection location --need help
Blower motor connection location --need help
Hello again fellow TL'ers,
I've got a question that hopefully will be easy to answer for many of you.
I have a 96 TL whose blower fan stopped working Friday. From my Mitchell CD, and from your posts in the forum, I have gathered that changing the blower motor is a ridiculous task. BUT, first, from the CD manual I have, it details exactly how to check to see if it is your blower motor that is bad first.
Quote "Blower Motor does not run
1) Check fuse No. 17 (30-amp) in underhood fuse/relay block and fuse No. 7 (7.5-amp) in underdash fuse/relay block. If fuses are blown, replace fuses. If necessary, repair short(s) to ground. If fuses are okay, connect jumper wire between blower motor connector Blue/Red wire terminal and ground.
2) Turn ignition on. If blower motor runs, go to step 6). If blower motor does not run, disconnect jumper wire and blower motor connector. Check for voltage between blower motor connector Yellow/Black wire terminal and ground. If battery voltage exists, replace blower motor. If battery voltage does not exist, turn ignition off.
etc.....
Obiovusly getting the blower motor out is tough becasue you have to remove the evaporator (drain your a/c etc..) But my question is where exactly are these blue/red and yellow/black connectors located? I don't think acura would make you remove anything to be able to get to these to check the motor. I already soldered myself up a nice 10 ft jumper cable (with one end with a large alligator clip just for the negative terminal on my battery.
Please help (and I pray that my motor runs so I can go on to the next steps without having to change the blower motor).
Thanks guys and gals,
Phil

My 95-98 Honda Shop manual shows the connector under the dash, behind the glove box. From picture it appears to be fairly high under the dash. You may have to remove the glove box to access. A good light and sometime upside down under the dash look to be only way to know.
I would be very careful to insure you connect to the motor side of the connector and not the power supply and/or ground supply side. The ground is provided through the climate control unit to provide variable resistance for infinite speed control. If you get wrong wires connected, you could blow the climate control ($$).
A less risky option might be to check for power to the motor on the Yel/Blk supply side wire w/ keyswitch on and blower on manual high. Use a Volt-Ohm Meter (VOM). If you have power, then also check for ground on the blu/red wire (again supply side not motor side). Either way you have to figure out which is supply and which is motor side. If both power and ground are available, then motor is bad.
Your proposed check could verify the fan motor is good, but would not tell you where the problem lies. You would still need to check whether power or ground is missing.
First thing I did when I recently purchased my 97 Acura 2.5TL was purchase (~$70) the Honda shop manual covering that model. I also have a Mitchell on Demand CD and it's not nearly as useful on most DiY problems. I've found too much information is much easier than too little.
good luck
