Windshield wipers on 99 Jetta TDI working, but barely...sluggish
Hi...Our windshield wipers just barely work. When my hubby gets the RPMs up, it seems to help, but still not normal. We've had the wiper motor replaced (twice), so it seems unlikely that its the same thing. What should we be looking at as potential problems? If its a relay, how do you know if its bad? Do I test, check for continuity, voltage, amperage, resistance? Is there any way to test for the problem without simply replacing any component it might be, unless its a cheap component (are there any cheap components on VWs?)
Winter is upon us, and I appreciate any suggestions...we're at a loss, and so is our mechanic (who isn't as familiar with VWs and diesels as we'd like). Thanks in advance!!!! Sandy

Windshield wiper motors are generally easy to replace. You need to remove the windshield wipers and take off the small grill panel above the hood and under the windshield. You should see the motor in there. It simply unbolts and unplug the electrical connector and replace it with a new one.
YOU NEED TO TURN OFF RADIO FIRST THEN DISCONNECT NEGATIVE BATTERY CABLE. YOU NEED TO MARK POSITION OF THE WIPER ARMS ON THE WINDSHIELD YOU CAN USE WHITE OUT LIQUID PAPER TO MARK WIPER ARMS LOCATION.THEN REMOVE WIPER ARMS,REMOVE THE COWL COVER,REMOVE THE WIPER MOTOR LINKAGE MOUNTING BOLTS.REMOVE ASSEMBLY, DISCONNECT THE ELECTRICAL CONNECTOR AND UNBOLT THE MOTOR FROM THE LINKAGE.
first try the fues box see if you have a blown fues, next if you put your wipers on can you hear the motor running for them? if you can the linkage has poped off from the motor, its a bit awkward to get it back on and no gaurentee that it will saty on, you might have to replace linkage, or, it might be the cogs on the actual wiper arms have splayed and are now smooth so they dont grip to move, you can take them off by the nut on the arm , get a can (coke can or simular) cut a rectangle out of it the hight and width if the cog, rap it round the cog, (make sure it does not overlap on the ends) and force the arm back into place and then do the nut up, this is just a short quick fix if that is the case you will have to replace the motor, also you can check the relay to the motor in the fues box, give it a tap a couple of times it might work again if not replace it...hope you find these sugestions helpful
