I press my on switch on my cruse control and every time I press set speed switch it just blinks when I keep pressing. ford 2003 sport trac


Most likely the servo has gone bad, but it could also be the clockspring. Go to the last page at the link to see the what the switches in the steering wheel should look like at the connector below the steering column. Use an ohmmeter at the connector to verify the switches and clockspring are good. Also check for shorts between wires that should not be connected.

My cruise control does not work on 1994 Ford 150. Fuse is fine, where to look next? Thank you


Which fuse ? There are two that supply B+ to the speed control servo ! One is located in the under hood fuse box and the other in the fuse panel inside the vehicle > The fuse may look fine but is there B+ voltage across the fuse . Check it with a volt meter . Check B+ voltage at the speed control servo , Black with yellow trace and P/O wire , what ever color that is . Is there B+ at the control switch ? The speed control servo supply's voltage to the cruise control switch . You can check it at the speed control servo as well . They could be videos on youtube showing how to test it .

My 2003 Ford Focus would not accelerate, and kept dying on me, now wont start, do you know what could be wrong?


A strong possibility of a defective Throttle Positioning Sensor (TPS)...It can be tested with a volt meter...TPS is located on the throttle body (see diagram below) & has a three pin connector with following wire colors; Brown (ground)...Yellow (+5 volts)...And White (TPS output)...Set meter to 5 volt dc...Push point,of safety pins into the Yellow and Brown wire at rear of connector...Do not disconnect connector...connect + lead to Yellow pin and - lead to Brown pin...Turn key on...Meter must read at least .08 volts...Open throttle full...Meter must read at least 4 volts...If not TPS is defective...Send results...NOTE>>>Diagram is based on a 2.0L Single Overhead Cam Engine, if your vehicle is different let me know...saailer

My cruise control does not work on my 2003 Ford Focus


Hi Fred,

There are several things that can cause your cruise control to not function. Anything from a bad speed sensor to a faulty speed control servo. It is impossible to tell you what is wrong without diagnosing your speed control system. Here is a quote from the vehicle manufacturer regarding this issue:

"Start by running speed control servo integrated self test diagnostics. The servo has integrated self test diagnostics which is a key tool in quickly and accurately diagnosing speed control system faults. Self test diagnostics are also the basis for starting speed control trouble shooting."

Please note that a diagnostic scan tool capable of accessing the speed control data is required for performing this task.

Cruise control indicater lights are on but will not engage


Check the cruise control module connector, see if it looks good and there is power to the module over one of the white wires in the 10 pin connector.
There are two white wires going to the module which is located at pins "G" and "J". There should be no voltage at pin "G" until the brake switch is applied. This switch is also used to operate the brake lights. The two wire colors on this switch are white and orange. At pin "J", this signal goes to the PCM to tell it that the cruise control module is engaged. Here is the info on the cruise control connector:

Pin A: gray - cruise control on switch signal: 12VDC with cruise switch on
Pin B: dark blue - cruise control set/coast switch signal: 12VDC with switch pressed
Pin C: gray/black - cruise control resume/accel switch signal: 12VDC with switch pressed
Pin D: brown - cruise control release signal: 12VDC with brake pedal not pressed: 0V when pressed
Pin E: black/white - ground
Pin F: brown - ignition 3 voltage: 12VDC with ignition on
Pin G: white - stop lamp switch signal: 0V with brake pedal not pressed: 12VDC when pressed
Pin H: dark green - cruise control inhibit signal: 0V if PCM detects an inhibit condition
Pin J: white - cruise control engaged signal: voltage (unsure of value, either 12VDC or 5VDC) when signal engaged
Pin K: dark green - vehicle speed signal: 1 to 5 volts depending on speed

This view of connector is facing it after it is separated.

Trying to post the connector view, the lines may not quite line up, but at least it should show you the pin positions.

Code 34 is set when the computer does not detect a voltage to and through the speed control servo. The cruise control computer is built into the PCM, which grounds two windings in the servo mechanism to regulate the vacuum applied to the servo diaphragm.
Note: All Chrysler corporation fuel-injected engines have the computer circuitry and software for the cruise control system installed, even if there is no cruise control installed on the vehicle. If there is no cruise control installed on the care or truck, the computer will interpret this as an open winding and set code 34.
First: turn the key ON, turn the cruise switch ON, and look for +12 Volts on the dark blue/red wire that connects to the servo mechanism. This circuit is fed:
  • from the ignition switch through to 10 (dark blue wire)
  • from fuse 10 to the steering column (white/red wire)
  • through the clock spring to the cruise control ON/OFF switch on the steering wheel (white/red wire)
  • back through the clockspring to joint connect "C" (yellow/red wire)
  • to the brake lamp switch under the dashboard (yellow/red wire)
  • through the firewall from the brake switch (dark blue/red wire)
  • to the servo (dark blue/red wire) A break anywhere in this path (broken wire, bad brake switch, loose connector, etc.) will interrupt the 12 volt supply to the servo and set a fault code. Work backwards until you locate the break.
Turn the key OFF. Unplug the the connector from the servo and measure the servo coil resistances.
  • measure the resistance between the servo pin that connects to the tan/red wire and the servo pin that connects to the dark blue/red wire.
  • measure the resistance between the servo pin that connects to the light green/red wire and the servo pin that connects to the dark blue/red wire. The resistance in both cases should be above 0 ohms and less than infinity.
Disconnect the battery(s). Unplug the 60 pin connector from the PCM and check for continuity between the pcm connector and the servo connector for the tan/red wire (cavity 33) and the light green/red wire (cavity 53).
If no wiring problems are found, check the PCM connectors for corrosion, and reconnect. Reconnect the battery and test the circuit again. If the problem still exists, the PCM is probably bad. NOTE: Personally, if the truck was out of warranty I would try to find for a used servo before buying a new PCM.

Alternator ligth staying on even after replacing alternator


The alternator is controlled by the PCM. Check the wiring to the PCM and also the power to the alternator. Sometimes when they go bad they will blow the fuse that supplies power on the three pin connector.
