Warnings

Tools required

Parts

• Windshield wiper switch × 1 — Use OEM specification or equivalent for 1970 AMC Rebel
• Wire terminal connectors × 1 — As needed if damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery cable to isolate electrical system
3. Allow instrument panel area to cool if vehicle was recently operated
4. Gather replacement switch and verify correct application for 1970 AMC Rebel

Procedure

1. 1

   Remove instrument cluster bezel
   Remove the screws securing the instrument cluster bezel trim panel. On the 1970 Rebel, there are typically four Phillips head screws along the perimeter. Carefully pull the bezel forward to disengage any retaining clips and set aside.
2. 2

   Access wiper switch location
   Locate the wiper switch on the left side of the instrument panel. The switch is typically mounted below or to the side of the instrument cluster. Note the position and orientation of the switch for proper installation of the replacement.
3. 3

   Document electrical connections
   Before disconnecting any wires, photograph or sketch the wire connections to the wiper switch. Note wire colors and terminal positions. The switch typically has 3-5 terminals depending on wiper motor speed configuration.
4. 4

   Disconnect wiring harness
   Carefully disconnect the wiring harness from the back of the wiper switch. If individual spade connectors are used, gently pull each connector straight off the switch terminals using needle nose pliers if needed. Avoid pulling on the wires themselves.
5. 5

   Remove switch mounting hardware
   Remove the switch retaining nut or screws from the front of the instrument panel. The switch may be secured with a hex nut behind the knob or with mounting screws from behind. If a knob is present, it may pull straight off or require a set screw removal.
6. 6

   Extract old switch
   Pull the wiper switch forward through the instrument panel opening. Maneuver the switch and attached wiring carefully to avoid damaging surrounding components or the opening in the panel.
7. 7

   Inspect wiring and terminals
   Examine all wire terminals for corrosion, burns, or damage. Check the wiring harness for fraying or deterioration. Clean terminals with electrical contact cleaner if necessary. Replace any damaged terminals or repair damaged wiring before installing new switch.
8. 8

   Install new wiper switch
   Insert the new wiper switch through the instrument panel opening from behind. Align the switch shaft with the mounting hole and position the switch body properly. Ensure any locating tabs or flats on the switch shaft align with the panel opening.
9. 9

   Secure switch mounting
   Install and tighten the switch retaining nut or mounting screws. If using a retaining nut, tighten firmly by hand plus approximately 1/8 turn with a tool. Do not overtighten as the panel and switch housing may crack.
10. 10

    Connect wiring harness
    Reconnect all wiring to the new switch terminals according to your documentation from step 3. Ensure each connector is fully seated on its terminal. Push connectors straight onto terminals until they click or bottom out. Verify no bare wire is exposed at connections.
11. 11

    Reinstall instrument bezel
    Position the instrument cluster bezel back onto the instrument panel. Engage any retaining clips first, then install and tighten all bezel mounting screws. Ensure the bezel sits flush and does not interfere with switch operation.

Reassembly

1. Reconnect negative battery cable
2. Verify switch knob operates smoothly through all positions without binding
3. Check that instrument panel bezel is properly aligned and all mounting screws are tight

Verification

• Turn ignition to accessory or run position without starting engine
• Test wiper switch through all positions: off, low speed, high speed, and intermittent if equipped
• Verify wiper motor responds correctly to each switch position
• Check that wipers park properly in the off position
• Confirm no electrical issues such as blown fuses or inoperative circuits
• Test washer function if integrated with wiper switch
