VIN TMBKF75L6A6029066.

Wiper parks either..... 1. against body or2.  just above ( think it is normal....every second sweep parks position 1. then position 2, then 1. etc.).

It became erratic as to whether it would wipe again after parking......this whichever position it was parked in.  A nudge on the wiper arm would get it going again.

Recently failed to move even after nudging.......but push/pull of base of wiper arm towards and away from glass (i.e. moving motor spindle in and out of motor) and it started and carried on normal behaviour for days and luckily for the MOT.

I therefore suspect a parking switch in the motor (or brushes, if it is not a brushless motor, becoming stuck in holders or just worn down).

I have just done a full rebuild of a 1980 Lucas wiper motor for my other car, which included cleaning built on parking switch contacts, new brushes, repair badly burned brush holder mounting plate and cleaning/greasing and now working well.

I suspect Yeti will require new motor (with built in parking switch?) BUT BUT BUT have see the part number 5J7955711 has 3 different suffixes -  A, B, and C.  

I do not want to risk burning out the column switch/control system by plugging in a wrong motor (perhaps with different order of wires in plug).  

Does anyone know what the difference is between the three motors with same part number but different suffix?

5J7955711A

5J7955711B

5J7955711C

 

Have emailed Skoda cust svc UK, 26 Mar, asking what difference is but so far (3 APR) only an automated generic reply of no help whatsoever.

I have seen 2 makes of motor advertised but neither says which suffix it is compatible with.

 Which of the 2 makes would be likely to be more reliable - Magneti Marelli or Febi Bilstein?

 

Self isolated in isolated Devon countryside.......Dennis

All 3 and the numbers shown are the same.
The different suffix shows updates to the parts for reliability or production costs etc during the production run.
I would always use the latest and if ordering one that's what you will get.

Wiper arm freed up and removed/greased and temporary back on.

Still no reply from Skoda UK.

 

Can anyone recommend which make would be better / more reliable - Magneti Marelli or Febi Bilstein.

 

 

They're all designed to the same specifications / drawings supplied by Skoda / VAG, so quality is unlikely to vary across the two different manufacturers.

 

Whichever manufacturer is supplying the latest version (5J7955711C) is the best one to go for.

 

Skoda's design of routing the washer fluid supply through the motor casing and having the fan jet that blocks quite easily right next to the motor spindle was never the best idea.

 

Hopefully iterations B and C have gone some way to improve the problem slightly.
