This is form your multifunction switch going bad or the wiring hard shell that plugs into it. 2002 should already have these parts released to an after market parts store. The plastic steering column comes apart very simple with screws. and the multifunction switch just unbolts. Don't let it scare you it is not hard to change it just unplugs. but you should check the wiring before you go buy the switch. Hope this helps

W202 wiper and horn both start occasionally


These problems are difficult to find, but not impossible. The wiring harness will have to checked at the following points. Check the fuse unit. (Clean all connections on the fuses and contact points.) Trace the connections from the horn to the firewall. If that is fine, check the connections from the wiper to the firewall. Inspect the wire harness loom that goes through the firewall towards the steering wheel. Inspect the "kickdown" switch underneath the accelerator. Test the switch for continuity. If the problem is still unresolved, check the relay panel and all relays for corrosion on any connectors. Be sure to inspect all earthing points on the body.(brown wire). This will take you a couple of hours to work through. Always tidy the wires after inspection and use proper solvents when cleaning contact points. I had a similar issue with my W124, when turning on the lights, the wiper started to work. I found the problem caused by a short on the headlight unit when I was working on the car. Good luck, I hope you find the problem soon.

When the key is turned wipers come on, and the right turn signal blinks fast. We think it might be a short in the wires but can't find out where. Is there something else that could be causing the

Technically, the wipers and turn signals are on two different circuits. But its possible the wires have melted together. One place to look would be in the steering col where the wiper switch and turn signal switch come together.
You could try unplugging the harness to see if the wipers still run.

Wiper motor only works on high. I changed the motor, but it still does the same thing.

I do not believe the selector switch has a replaceable resistor for speed selection. You can try turning your switch to low speed and testing for voltage signal at the wiper motor. If no voltage, turn to high. If voltage, either bad switch or broken wire in harness. Tilt steering wheel up and down with wiper speed on low. If you get any wiper movement, probably broken / shorted wire in steering column. If not, bad multi function selector switch. Switch is in the $200 range plus labor to replace.
If replacing your self, caution must be used to disconnect the battery and pull the air bag fuse, as steering wheel and air bag assembly must be removed in process and you do not want the air bag to accidently deploy. A great step by step video for replacement is here:

Turn signal fuse pops when tilt steering moves positions or when shifter is moved in to reverse. problem is either in wiring in steering column or turn signal switch as far as i can tell or can this be...

If both ways cause it, I would say check them steering both. The problem is in the wiring harness though. You probably can see melted wires.

I have a 2003 ford windstar and the wiper wire harness melted any ideas if the computer would cause this

No the computer would not cause this. Wires only melt when the power being forced through them is more than the wire can handle. The excessive power draw is caused by a short or a bad motor with improper fuse protection.
