What is the fuse number for the dashboard lights on a 2007 Ford Focus 3 door hatchback?


Principles of Operation
The instrument cluster and panel illumination consists of dimmable and non-dimmable illumination components. The dimmable illumination is controlled by the instrument panel dimmer switch, which allows the brightness level of the backlights to be adjusted to the customer preferences. With the parking lamps ON, the instrument panel dimmer switch uses electronic circuitry to provide a variable pulse width modulated (PWM) output to the instrument panel and all applicable switches depending on the driver-controlled level of intensity. The headlamp switch backlighting consists of 2 constantly illuminated LED bulbs that are powered by separate circuits. Battery voltage is supplied to the first bulb when the ignition switch is in the RUN position. Battery voltage is supplied to the second bulb with the parking lamps ON. The non-dimmable illumination allows for full intensity dependant on the ignition switch position.

Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Headlamp switch
  • Instrument panel dimmer switch
  • Circuitry
  • Connector(s)
  • Headlamp switch
  • Instrument panel dimmer switch
  • Illumination source(s)

  1. If an obvious cause for an observed or reported concern is found, correct he cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, verify the symptom and GO to Symptom Chart .

  • The instrument panel illumination does not dim
  • Headlamp switch
  • Circuitry
  • Go To Pinpoint Test H .

Pinpoint Test B: The Instrument Cluster Illumination Is Inoperative
Normal Operation A variable pulse width modulated (PWM) voltage is supplied to the instrument cluster through circuit 29S-LA31 (OG/BU). The instrument cluster is grounded through circuit 91-GG14 (BK/OG).
    Possible Causes
  • circuit 29S-LA31 (OG/BU) open
  • circuit 91-GG14 (BK/OG) open
  • instrument cluster
PINPOINT TEST B: THE INSTRUMENT CLUSTER ILLUMINATION IS INOPERATIVE CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.

Heater wont turn off


More than likely the switch on the climate control panel is bad, most vehicles have a relay behind the or attached to the climate control panel that you can change out. If not you may have to go to a auto parts store or a junk yard for a replacement climate control switch. Hope it helps.

What could be wrong with my 2001 f350 v10 climate controls that the fan only works on high and the blend only works in defrost no matter what is selected?


Almost sounds like your climate control switch is bad as it controls everything including the switching and blower speed with the exception of the blower speed being a blower resistor issue (allows multiple speeds).

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Ac compressor wont kick on when running air Full of refrigerate to! jumper wire to compressor and ran! What is it Ac relay or wiring?


It could be the fuse, climate control, switch, or relay.
If you check at the switch, that will also tell you if the fuse might be bad.
Then if you check at the relay, that will tell you if the climate control is bad.

f that just put power to the blower moter and see it it runs if you pull the relay jump a wire across the terminals with it out and add a ground wire to the case of the blower to another spot on the chasis if it still does not run your blower switch may be bad dont worry just run a toggle switch to a good blower moter
