Notice: This message contains informative content based on first-hand experience rather than speculation and conjecture. I had occasion to remove my wiper control module the other day (after 150K miles in Oregon rain, the relay contacts were finally too carbonized to make good electrical contact). The service manual instructions for this procedure reads something like "remove 2 screws securing module." Although the service manual is correct that the module is secured with 2 screws, the instructions trivialize the procedure and are wholly unhelpful if you actually find you need to remove the module. After having removed my module, I thought I would share the simplest procedure for doing so. This procedure applies to the winshield wiper control module, the hazard flasher unit, and the buzzer box which are all mounted to the same sub-panel. The panel is mounted above the steering column under the dash on the driver's side. Step 0 (optional): If you have a large frame and find the driver's footwell to be a tight squeeze, remove the driver's seat. I'm small- framed (although reasonably tall) and found no reason to remove the seat, but for someone that is large framed, removal of the seat gives you a lot more maneuvering room. Step 1: Remove the rubber gasket from around the dashboard air duct that mates with the door duct when the door is closed. Step 2: Remove the plastic air duct trim piece and retainer that the rubber gasket was attached to. Over the years the plastic has become brittle, so removal of the plastic piece must be done with care. There are 2 tabs on the plastic piece that must released slightly in order to allow the piece to be removed. Step 3: Remove the round duct that was attached to the plastic retainer and trim piece. With the trim piece removed there is sufficient play to allow removal of the round duct. Step 4: Working underneath the dash, locate the plastic duct that connects from the central console area to the round duct just removed. The plastic duct is held in place with a U bracket that is secured with two screws. Remove the two screws and the U bracket. Step 5: Working underneath the dash, release the plastic duct from the console side and remove the plastic duct by threading it out towards the driver's side of the footwell. Step 6: Working underneath the dash, the subpanel is now accessible. The subpanel is located above the steering column and is accessible from the driver's side. The subpanel is snapped in place using clips and the entire panel can be removed by pulling it loose. There is sufficient slack in the wiring harness that the panel can be pulled free and brought down into the footwell. Step 7: With the panel hanging in the footwell, the wiring harness connectors can be removed and the entire panel freed. Step 8: NOW you can remove the wiper control module by unscrewing the two screws that secure it to the subpanel (as indicated in the service manual). I hope someone might find this helpful. Knut
