Hello Everyone,

My 04 SC Lariat 150 cruise control sometimes engaged (well for the most part it doesn't). I read somewhere that this could be a result of a faulty/defective Brake Interlock Switch which also affects the operation of the window. Well the last time I tried to roll-down my rear passenger window, it wouldn't come back up. I fiddle with it and finally got it up after I jumped the actual regulator using a 18v battery from my rechargeable drill.
Anyway, I have since bought the interlock switch but need some direction on how to replace it or at least gain access to it. I have the center floor shift console. If you happen to have pictures or reference on how to remove it, please post them. I'd like to get this fix this weekend.

Thanks in advance...

 

The brake switch for CC is on the actual brake pedal, up under the dash.

Removal and Installation

CAUTION: Do not press the brake pedal when removing or installing the speed control deactivator switch or damage to the switch will occur. Disconnect the speed control deactivator switch electrical connector.
Rotate the speed control deactivator switch counterclockwise 45 degrees and remove it.
NOTE: The speed control deactivator switch is self-adjusting. Do not press the brake pedal during installation. Initial installation of the speed control deactivator switch allows for one adjustment. If additional adjustments are necessary, install a new speed control deactivator switch. To install, reverse the removal procedure.

 

I actually found it, in my SC, it was directly under the shifter.

 

I am having the exact same issue. how did you get to the switch?
