I have a 2004 Volvo XC90 and the wipers have stopped working the wiper motor was replace and a new wiper switch and they still don't work any clues to what is happening

Replace the gem module / fuse box that houses the fuse for wipers under driver side of dash. As it most likely burned up a circut path in the box enough to not let low power thru....possiable bad wiper control or partial failed wiper relay.

Bad relay that's your problem Regards Chris

replace the fuse,or the switch

either faulty wiper switch or wiper motor , need to be checked by a auto electrician

check wiper relay

This is the wiper motor failing...But to be safe unplug wiper motor,turn on wiper switch,connect test light to negative side of battery or good solid metal ground and stick probe in connector.if it is not working and the test light is not on then the wiper switch has failed.....and if the test light comes on at connector the wiper motor has failed..Since it works intermittently have an assistant to work the wiper switch and test a number of times to be sure.You can buy a cheap test light that will be good enough to check this at any auto parts store...BEFORE YOU BEGIN YOUR TEST MAKE SURE TEST LIGHT
HAS GOOD GROUND BY CLAMPING TO NEGATIVE SIDE OF BATTERY AND TOUCH PROBE TO POSITIVE SIDE OF BATTERY TO ENSURE GOOD CONNECTION...LIGHT WILL COME ON.

time for wiper motor assembly..

HI. This is a possible motor issue. To confirm, use this procedure. it will help isolate the actual issue at hand.

1.Make sure the battery has a strong charge and is in good condition. Use a voltmeter to get a reading if necessary.

2.Connect a jumper wire between ground and the wiper motor. Turn the key on but don’t start the engine. Turn the wiper switch on. If the motor works, check for a corroded or loose ground connection.

3.Turn on the car key but don’t start the engine. Turn on the wipers. Check for voltage at the wiper motor with your voltmeter. If you get a good voltage reading, turn the key off and disconnect the motor from the wiper linkage.

4.Move the wiper arms by hand. If they are stuck, you have found the problem. If the wiper arms move freely by hand, go to step 5. If voltage is not reaching the motor go to step 6.

5.Remove the wiper motor by disconnecting the plug and removing the bolts using a wrench or ratchet. Use a pair of jumper wires to connect the wiper motor directly to the battery. If the motor does not work, replace it.

6.Turn on the key but don’t start the engine. Get a voltage reading across the wiper switch. If there is voltage, use a jumper wire to bypass the switch, if the motor works now, replace the switch, otherwise go to step 7. If there is no voltage at the switch, go to step 8.

7.Check for continuity at the wire between the switch and the motor. The wire could be loose or disconnected.


8.Check the wire coming from the fuse panel to the wiper switch. It could be disconnected or loose.

It's the part which contains the electrical connections and the park switch.

my 2004 expedition had same problem, if you take apart the shaft that goes thru the glass it will be full of dirt, clean ,lubricate and reinstall, you may have to replace the O-ring on the shaft. a 20 minute job, very easy fix
