98 ford expedition wiper problem

check the linkages at your wiper motor. check the wires for power to the motor.

Check the attaching nut for the wiper blade. They will come loose over time. Pop up the cover on the wiper ,there is a 13mm nut try tightening it. Make sure the wiper arm and motor are in the park position before tightening.Good luck.

my 2005 ford exp rear wiper moves but the wiper does not it look like something is missing to make it move back and forth can you help.

• Central junction box (CJB) Fuse 211 (15A), Fuse 215 (30A)
• Multifunction switch
• Wiper run/park relay
• Wiper high/low relay
• Windshield wiper motor
• Circuitry
• Battery junction box (BJB)
• CJB
• Generic electronic module (GEM)

-------------------------

1. check the fuse to the rear wiper motor
2. check for power to rear wiper motor at the motor (power wire going in to the wiper motor with rear wiper switch on)
If you have good fuses & have power going in to the rear wiper motor...
3. Pull old rear wiper motor and install a new rear wiper motor.
Thank you please drive thru......

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

THEN THERE IS BUT ONE EXPLANATION, THE WIPER TRANS IS NOT CONNECTED TO THE MOTOR DRIVE HEAD.

if motor is running check for striped arm or bushing look at the arm that hooks to motor whats it doing see if drive arms are turning with motor they will be short

don't have to remove the dash- remove the plastic black cowl just under the wipers. The "pop" you heard is probably the clasp coming off the ball nut connected to the wiper motor. check the mounting plate for damage (usually they're good or need a little bending-needle nose pliers work best). Screw the two nuts back down after you reposition the unit. Turn on wipers to test connection, but make sure wipers are clear before testing. Replace cowl and you're back in business.

The motor is usualy central to the wiper arms and either bolted to the firewall or inside the plenum chamber at the bottom of the windscreen.If you can hear the motor you can find it, track it down by listening.Your probly right about linkage however if that is the case you should be able to move the wipers with your hand and they should move freely if they dont you may have other problems.
