Slow windscreen wipers .... troopy

Post by V8Patrol »

Is this a common fault ?
both my troopy and the fatherinlaws troopy does the same thing........

when initally turned on the blades take forever to move accross the screen..... 6~7 seconds per swipe ( 12~14 secs for a full circut)
:shock:

changing the wiper speed has NO effect, they still wont wipe at a normal speed, just this slow almost struggling action.

After 10 minutes of opperation they begin to act like a normal wiper :?


Even switching them off for a few minutes and then turning them back on sees the same thing happening...... dead slow action that eventually comes good.


I'm guessing theres an issue with a bush for the arms or motor but want some tips before I start pulling it apart.

My HJ75 got so bad I bought a second hand wiper motor from Private Parts 4x4 in Sydney and swapped out the motors. It cured the problem but I have not pulled the wiper motor apart yet to see what was causing the problem. My wipers struggled like yours until they were obviously going to stop or burn something out trying to get going. regards

Most likely cause is a wiper motor that needs a few drops of oil on its bushes.

Have come across quite a number now that responded well to removing the motor.
Often no more than 3 bolts, earth wire, and pop out the knuckle joint from the wiper mech, remove cover, and a few drops of light sewing machine oil, castrol handy oil, you know what I mean etc, ,and a quick clean of the armature where the brushes wipe to remove excess dust etc.
There are 2 bushes, one at each end of the motor.
Another place where they can bind up is in the wiper posts, the supports that are under where the wiper arms are bolted to the shaft.
Dont be lazy and just oil these, they need to be removed and the shaft taken out, cleaned of the build up of dry grit and gunk, and regreased.
Far better results after those are looked at.

Also make sure you wiring is in good condition, no corrosion etc, but most likely its the motor, and the support bushes binding on the wiper shafts.

hope that makes sence.
