The 1995 and up Jimmy’s and Blazer’s use thesame system for engaging the front diff. They are all made to “shift on the fly” while driving down the road withnothing to do but press the button on the dash. (Do NOT shift into 4 Low while driving at higher speeds at it can dodamage). If the dash light flashes andyou hear a clicking sound that means you have power to the relay. If the vehicle 4 High lights stops flashingand it goes back into 2 High then the problem is likely that you have no vacuumto the 4 X 4 actuator module which is located below the battery tray. Remove the battery and tray; look for a holeburnt in the vacuum line or actuator module rubber diaphragm. When the activator get vacuum it pulls acable that attaches to the front diff engaging it, when engaged the wires onthe front diff send a signal to the 4 X 4 light on the dash telling you it is engaged). If the battery has ever leaked the acid runsdown onto the actuator causing the problem. If no holes found in the hose or actuator diaphragm I would use batterycables and hook up the battery and start vehicle then check for vacuum byputting my finger on the end of the actuator hose. If there is vacuum then problem in actuatoror cable linkage. If no vacuum I wouldthen trace back the vacuum lines to find where it is off or leaking, NOTE: As the heater control operates on vacuum and some other vehicle systemsdo as well bear this in mind, has your vehicle had heater control problems orbeen running rough, this could explain a lot of potential problems. Attached to the hood on the left side(drivers side) on 1997 and older models is a vacuum (a “ball”) canister, newermodels the canister is located in the left fender by the brake module, makesure the vacuum line is attached there. Please rate this suggestion as I never know if it is worth my timefilling these things out…

SOURCE: 4x4 transfer case oil change for 2007 Chevy Tahoe

Go buy the chevrolet shop manual for the truck. Its worth every penny in the long run and will save you thousands by not going to the dealer for everything, because they consult the shop manual. make sure your tranny doesnt share fluid with your transfer case, you could over fill or underfill it easily.

Headlights 2000 Chevy astro van dont work they come on some times but go right off i think theirs a ground loose or some thing new battery new alternator


I'd check the headlamp relay in the under hood fuse / relay box to start . The relay is energized by the BCM - body control module !
Voltage is available to the headlamp and panel dimmer switch at all times. When the headlamp and panel dimmer switch is activated, the two following actions occur via CKT 352 (WHT):
?€¢
A headlamp enable request is sent to the body control module (BCM)


?€¢
The headlamp relay is activated

The VE1 option is equipped with automatic headlamps, which is activated when the photo sensor detects dark conditions. A code will set if there is a fault in the photo sensor, or in the two CKT's between the photo sensor and the body control module (BCM).
The coil output of the headlamp relay travels through CKT 250 (BLK) and is grounded at G101.
When the headlamp relay is activated, power is supplied to both the LH and RH headlamp fuses through CKT 1346 (LT BLU).
LO and HI beam functions are activated/determined by the multi-function switch on the steering column.
The HI beam function must be enabled by the body control module (BCM).
The headlamp power travels through the multi-function switch at the steering column and is grounded through CKT 750 (BLK).
The flash-to-pass function is also activated by the multi-function switch on the steering column. It is powered by CKT 1840 (ORN) and enabled through the body control module (BCM) via CKT 307 (YEL).

2002 ford expedition interior lights are not on what fuse is it?


Courtesy Lamps - central junction box. fuse # F1.21 that goes to interior lamp relay in the instrument cluster and F.24 this fuse powers battery saver relay .
Interior Lighting The interior light system consists of the following:
  • front map lamp assembly
  • front door courtesy lamp
  • generic electronic module (GEM)
  • glove box lamp assembly
  • central security module
  • interior lamp switch
  • interior lamp relay
  • illuminated vanity mirrors (Navigator only)
  • reading lamp assembly
  • rear courtesy lamp
  • running board lamp
  • underhood lamp assembly
  • The generic electronic module (GEM) illuminates the interior lamps when an unlock signal is received from the remote anti-theft personality central security module. The illuminated entry feature will be canceled when any of the following conditions are met:
    • 25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is not activated (door ajar or courtesy lamp switch on).
    • The GEM receives a request from the central security module (remote transmitter lock button pressed) and the interior lamp control is not activated.
    • The ignition is in the RUN or START position and the interior lamp control is not activated.
    The GEM will illuminate the interior lamps when any door is open or ajar. The interior lamps are; the dome lamp, the rear cargo lamp, the door courtesy lamp and the side rail lamps. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps will not be reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp switch is received.
    The GEM controls the interior lamps illuminated entry function by activating the interior lamp relay.
  • You have an electronic control module and relays involved in the operation of these lights also !

    07 Tahoe - L/S Parking light fuse keeps blowing when tailgate is opened


    HI,
    You have a 'short to ground' wiring issue. Either the switch that is activated by opening the gate or the wiring in the gate itself is damaged/broken.
    I'd remove the switch 1st and see if the fuse doesn't blow. IF it does by a new one on Ebay or @ the dealer.

    otherwise, get a multi-meter and a wiring diagram for your Tahoe and trace the wiring from the switch.
