No. the switch has fuses. The fire was most likely caused from wiring it wrong. The fuses should have blown first.

How to remove multifunction switch and clean it.

Cleaning the switch is not possible - if it is malfunctioning, it needs to be replaced. You can check the various functions by disconnecting the washer/wiper cable at the bottom of the steering column and checking continuities, but you will need the wiring schematic (shop manual). In the meantime, you should pull the ACCY fuse (15a) in the underhood fuse box.

I have a 1998 Chevy tahoe that the parking lights will not shut off with the switch . The only way to get them turned off is by unhooking the battery. pulling the fuse wont even get them off... Whats

You've got a shorted switch. Change it. Try unplugging the switch and see what happens. You may have shorted wires somewhere. If you have a trailor hitch recepticle, check that for bad wiring also. Melted wires go unseen under tape or plastic protector sleeve. Mostlikely it's the switch for the headlights.

Can I put a trailor hitch on my Elantra. I want to tow a car dolly (empty)

They do sell a small hitch for light loads, I believe it is 1000 lbs tug weight max, that can be put on your vehicle. The best place to look for a professional installation would be someplace like pep Boys or U-Haul. I say this because of the way your bumper is made you can't really attach to that with a hitch. The hitch unit has to be welded to or bolted up to the frame itself which takes special equipment.

How do I replace the signal switch assembly on my 2004 Chevy Cavalier?

Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF , unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.
  1. Disconnect the negative battery cable.
  2. Remove the steering column trim covers.
  3. Remove the retaining screws from the multifunction switch.

    Fig. Remove the multifunction switch (2) from the steering column

  4. Remove the multifunction switch from the steering column.
  5. Disconnect the electrical connectors from the multifunction switch.

To install:
  1. Connect the electrical connectors to the multifunction switch.
  2. Install the multifunction switch to the steering column while depressing the spring loaded horn pin.
    NOTE Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  3. Install the retaining screws to the multifunction switch and tighten the screws to 36 lb inches (4 Nm).
  4. Install the steering column trim covers.
  5. Connect the negative battery cable.
  6. Ensure that the multifunction switch functions properly.

I need to know the requirments and how to wire in my towbar volvo v50 year 2006

The very best information I have ever gotten for tow bar wiring and even trailor hitch parts and installations have been from Budget truck Rental Locations.
Seems that is a major part of their business, installing tow hitches, bars, wiring, to conform to DOT rules and regs.
Hope this helps.
Happy Motoring!!

Where do i find the wiring adapter for the lighting wiring for a tow hitch

You may have a tow hitch but no wire harness? You gotta buy a trailor wire harness kit and may need a professional to hook it up because there are a lot of wires to deal with. Normally the hookup it mounted near the hitch it self, but my guess is you don't have one.

Rear turn signals don't work, bulbs are good, front signals blink fast, at first only drivers side didn't work occasionally, now neither side works at all. What's wrong?

are you sure bulbs are good ?? double check bulbs also make sure there is a ground wire from your light fixture is grounded to the body near by this might be causing your problem .. usually if front ones blink fast rear bulbs are bad ... thanks Jerry holler if you need more.
