Cruise Control

[zebz21]

Well i've had my truck for about a year now...and when i bought it the cruise control never worked..what are some possible reasons for this.. i hit the buttons and nothing happens

Just about any part not working correctly causes it just to do nothing.

You're going to have to go looking. Sorry, there really is no other way.

easiest solution is a steady foot

By any chance is your ABS light on too? If so check and see if Ford will fix it under Warrenty as a past defective part. I didn't find out about my 99 till I sold it.

nope..just check engine light...figure its the o2 sensors but too cheap to buy new ones. I am not to familiar with the cruise control. I know the fuse isn't blown because that's the first thing i checked. I didn't want to mess around with the buttons because I didn't want the air bag to go off.

Fix your check engine light before you go after accessories. They may be related.

NO code condemns any sensor by itself.

Self-Test Diagnostics

WARNING:
This test is a key on engine off (KOEO) test only that is conducted in park only with emergency brake fully engaged.

l Enter Self-Test Diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator lamp on the instrument panel will flash once to indicate that the speed control module entered the diagnostic mode. Five additional flashes at this point indicate a defective speed control servo. Release the OFF switch.

l Note:
If the ON switch is not pressed within five seconds after entering diagnostic mode, the module times out and the procedure must be started over.

Press the remaining switches in this sequence: ON, RSM (resume), CST (coast) and SET/ACCEL.

l The speed control indicator lamp will flash as each switch is pressed. Press each switch in the sequence immediately after the light goes out for the previous switch.

l After all five speed control switches complete the sequence, the indicator lamp will flash to indicate a pass or fail:

— 1 flash - Test passed (with dynamic throttle pull).

— 2 flashes - BPP switch is defective, circuit is defective or brake pedal is applied; CPP switch is defective, circuit is defective or clutch pedal is applied.

— 3 flashes - Brake deactivation switch is open or circuit is defective.

— 4 flashes - Vehicle speed sensor is out of range or not connected.

l Immediately after the static test has passed, the speed control servo will then perform a dynamic test automatically by actuating the throttle lever from 1 mm to 10 mm of travel from the idle position. During the dynamic throttle pull, observe throttle movement to witness any binding or sticking of the actuator cable, verify the correct connection of the actuator cable to the throttle lever, and make sure the throttle returns back to the idle position. If improper connection and/or binding or sticking of actuator is observed, go to Symptom Chart.

l Return the ignition switch to the OFF position and proceed to Symptom Chart.

FWIW, the first things I would check are:

Brake Master Cylinder Pressure Switch (these are the ones in the "recall" and are frequently disconnected by Ford, because they don't have any of their fused harnesses in stock)
Brake Pedal Switch
Clutch Pedal Switch
