Front windscreen wiper wont stop why its a mitsubishi lancer evo4 i was touching the windscreen washer pump which had ceased working wipers came on and wont stop have to take the fuse out to stop them

turn the wipers on fully and try tapping on the wiper motor, sometimes the brushes freeze...

Hi, First check that you have wash liquid in tank. second make sure that it will not freeze by putting alcohol in your mix of water and soap. You can buy it already mixed at most service stations. Check pump for corosion on contacts.
Good luck.

First time you must diagnose why windscreen wipers going slow and/or stopping.
In order to find out the cause of wipers stopping you can try follows:
1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!!
2. Disassemble the plastic covers from the bottom of the windscreen.
3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables.
4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encounter fault of the wipers running at Audi.
5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters.
6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation!
7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
Refit all in reverse order.

may have broken bushing in one of the arms in the wiper linkage, remove the cowl and take a look. most part stores sell replacement bushings start there good luck.

I had the same problem in my Saab. Replace the column with the buttons and you should be good to go. Check with eBay and local junk yards for the part.

check under the hood for a relay fuse.

pull the fuse if it wont stop, faulty switch or relay sticking. get it from the junk yard. more likely it the wiper switch is faulty.

check the end of the wiper. Under the cover at the end of the wiper there is a 10mm nut. it comes loose sometimes.

If it is the same as some other Chevrolets they have 2 pumps attached to the side of the washer bottle. 1 for rear and 1 for front windscreen

check the switch on the steering usualy it becomes faulty after a while and also your window washers could be blocked but try turning it on if you do not hear a buzzing sound the motors needs to be replaced.
