Is there a way to test if it is the switch or the motor?
odyssey2001ex said:The driver's side vent motor has been working internittently for the last few months but completely died last week. Today I decided to look into it. Here's what I did:
. Checked 7.5A fuse: was OK but I replaced with a new one (couldn't hear clicking noise when operating switch, with fuse removed)- no dice!
. Took out the paneling, unplugged vent motor and used voltmeter to test plug: I got 12v DC (engine off), 14.4 v (engine running). I think that's normal (or NOT?????)
.Unbolted vent motor, connected to a 9V battery - no dice!
.Took motor apart, cleaned up internal brushes,
put it back together, greased gears, arm, reassembled, connected to a 9V DURACELL battery and it works!
.Connected back to car - no dice
.Unplug, Connect back to 9V battery. It works fine! It opens and closes vent!(by reversing battery connection)
CRAZY OR WHAT? ANY THOUGHTS?
Ken W said:I've gotten into it with these lousy vent window openers. They were weak and seemed to fail intermittently.
I finally cracked open the cases on the vent window openers expecting to find a friction problem or wear on the set of gears that the motor turns to move the window. I found those parts to be a good as new inside so I dug deeper and removed the actual high RPM electric motor that drives the gears. The problem turns out to be cheap chinese electric motors. Hooked up to 12 volts they would sometimes spin with enough torque to feel by pinching between your fingers and sometimes not. Blowing out the motor with an airgun temporarily fixed it. But the bottom line is that these motors are complete junk. Could be bad brushes, poor windings, or sloppy toloerances. All Chinese trademarks.
(In fact, Patton Fans a former manufacturer of high quality USA made houshold fans, switched to Chinese motors in order to compete with the lo priced crap sold at Wal-Mart etc. The problems were immediate as observed on many consumer forums, but they stuck with the plan of selling well packaged crap until people stopped buying and the Company went under. The same story has been repeated ad infinitum in various industries. I worked for an American manufacturere of Hydraulics that did the same thing. After Shin Fu's poor quality control and lousy metallurgy put Lincoln Automotive on the blocks, Shin Fu actually bought us for pennies on the dollar just for the Lincoln name. Other divisions of the company were sold off and no employees were kept.)
I usually go to salvage yards for parts like these window motors, but since they can all be verified as crap, it's useless. DOES ANYBODY HAVE A CHEAP SOURCE FOR THESE ASSEMBLIES NEW? I'd hate to pay dealer prices for crappy crap unless They could promise me Honda has improved the motors.
My dealer adds 30% to the mfg's price, so I go on line to Majestic Honda in Lincoln, RI for all my factory-only parts:Ken W said:I usually go to salvage yards for parts like these window motors, but since they can all be verified as crap, it's useless.
