Your multi function switch is bad. Expensive dimmer, This require removal of the steering wheel and air bag so you can access the bolts holding the switch. Also requires you remove the trim pannels on the steering column.
Before you start all of this, disconnect the battery. 2. remove trim panels on steering wheel. Remove air bag and disconnect yellow wire and black wire by giving a 1/8 turn on the horn wire. Remove steering wheel, remove dimmer switch, you must take it apart to disconnect the wiring harness. Pull out the dimmer portion which has a nylon wedge. Ensure contacts on this are not melted. Clean contacts, ensure wedge is not broken. It has a little piece on the bottom to keep it in line. If its missing you need a new switch. When I get home will insert images so you can see what am talking about. Also when re-assembling ensure the plastic pinion is in the park position for the wipers, If your wipers start working before re-assembling the switch just move the pinion to the position where the wipers park. Ensure wiper on the signal lever is in the OFF position and re-assemble. These cars all suffer from this problem. I have been working on this issue over 2 weeks, Am down to tracing wires, which I gave an extensive explanation on how to do this. Look for it under the name of Angel Rondon. More to come as I keep going on.
