wipers not coming back to their resting place

Need your help to know what could be the reason for this before I visit the service station.

 

The wipers blades are not coming back to their usual resting place after choosing the neutral position. On sunday, I did a long drive to Mysore and encountered some heavy rains. It all worked fine then. On Monday, i got the car washed and went out in the evening. As it was still drizzling, I used the wipers. But, to my horror, the wipers are not coming back to their usual resting place. 

Has happened in my earlier M800 and was due to worn rubber. If you havent changed the blades in the past year, consider Bosch one--been using them for abt 8 months and are excellent. But a bit surprised coz fiat has a much powerful motor and should work quite well. Probably, worth your while checking the connections too. Rarely, overzealous cleaning can cause a bit of a bend/ twisting of the blades causing it to malfunction--could have happened as a result of the wash.

I had this problem one day with my Petra. The wipers work but would not return to the resting position. I started a reboot that evening. Connected the battery cable only the next day and the wipers returned to their normal position. The only other possibility is when the earth wire from the wiper motor gest disconnected. If this happens the"Auot rest" function does not work.

My palio has same issue. I showed it to service center last year and they do not  have any solution. I also observed that after long use, 1st and 2nd has same  speed. If you stop the car for 5/10 mins it works fine again. Since, i could not  find the solution, i decided to live with it.

Your Intermittent speed is not working. It is bcoz of the circuit fitted on the wiper motor.For that u have to change a whole wiper motor assembly.Sometimes it is caused due to moisture on the circuit.It is covered under extended warranty so you can just check it out.

I have been living with this problem for an year. I was told that the entire motor assembly needs to be changed, and it will cost me about 4-5k. I have now got adjusted to this problem.
