Question about 2004 GMC Envoy

Vauxhall Astra Envoy indicators not flashing

My mk4 Astra LH indicators do not flash but the RH side work fine. The flasher units operates at twice the speed indicating a faulty bulb. However I have swapped all the bulbs from the RHS to the LHS and the fault stays with the LHS. Only the RHS works with the Hazards. If you leave the indicators on for about 5 to 10 mins, they start to work. (it is like the more you use them the more they will work). The next time you use the car the fault has reappeared.

    Same problem on same model Holden (Vauxhall/Opel) Astra.

    LH indicators either don't work, flash twice the speed, or skip a flash every now and then. First noticed problem on Monday, worse Tuesday. Fine Wednesday. No LH indicators at all on Thursday, Friday worked perfectly (when i had it booked into an Auto Electrician who say they can find no fault!)

With out doubt it is the Indicator Flash Unit (Found near fuses) its a plug type box. you pull it out, plug in new one and it works. (Kinda looks like a strange adaptor plug you would put in a power socket.

The hazard back lights wont quit blinking when car is running even when i pull the fuse on a 2002 buick regal


What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

Right blinker not working 1999 Buick park avenue


You'll need to find a wiring diagram an component location chart to check this out . Here is a diagnostic flow chart for trouble shooting this problem ! Do you know how to use a voltmeter ?
DEFINITION: This table diagnoses inoperative turn signals on one side. It assumes that the cornering lamps, hazard lamps, and turn signals on the other side all operate properly.

1

Did you perform the Exterior Lights System Check?
--
Go to Step 2 - yes
Go to Exterior Lights System Check - no

2

  1. Disconnect the turn signal flasher connector.
  2. Turn the ignition switch to the RUN position.
  3. Place the turn signal switch in the appropriate position.
  4. Connect a DMM from the appropriate turn signal flasher connector cavity to ground:
?€¢
LH: cavity C (ORN)


?€¢
RH: cavity B (BLK)

Is the voltage within the specified range?
10-15 V
Go to Step 3 yes
Go to Step 5 no

3

Connect a fused jumper between the appropriate turn signal flasher connector cavities:
?€¢
LH: cavity C (ORN) to cavity D (YEL)


?€¢
RH: cavity B (BLK) to cavity F (TAN)

Do the appropriate turn lamps light without flashing?
--
Go to Step 4 yes
Go to Step 6 no

4

Replace the turn signal flasher. Refer to Hazard and Turn Signal Flasher Replacement .
Is the repair complete?
--
Go to Exterior Lights System Check
--

5

Repair the open in the appropriate circuit:
?€¢
LH: CKT 57 (ORN) between S200 and the turn signal flasher


?€¢
RH: CKT 58 (BLK) between S201 and the turn signal flasher

Refer to Wiring Repairs in Wiring Systems.
Is the repair complete?
--
Go to Exterior Lights System Check

6

Repair the open in the appropriate circuit between the turn signal flasher and the IP fuse block:
?€¢
LH: CKT 685 (YEL)


?€¢
RH: CKT 686 (TAN)

Refer to Wiring Repairs in Wiring Systems.

Rapid Continuous Flashing of Air Bag Indicator (No Diagnostic Trouble Code) Both Primary Crash Sensors Disconnected Assembly Plant Mode

TROUBLE CODE CLEARING

1. Follow the diagnostic procedures to service the fault condition flashing on the air bag indicator prior to code clearing.

2. Cycle the ignition switch to OFF and then to RUN.

3. Observe air bag indicator prove-out (six ? two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

4. Locate the Diagnostic "Trouble Code Clear" Connector (grey connector). located underneath the glove compartment, left side (06010) containing Circuits 631 (T/R) and 57 (BK).

5. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

6. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

7. Release short on Circuit 631 (T/R) to Circuit 57 (BK). This short must be released within 25 seconds after the diagnostic monitor tone sounds.

Diagnostic trouble code is now cleared from memory. Next highest priority diagnostic trouble code stored (if one exists) will begin flashing.

The codes and clearing proceedure above are to be used as a guide, NO claims are implied as to the correctness or accuracy of either.

Turn signal lights not working. turn on emergency flashers and the right signal flashes and bath back lights and the front right flash but the left front don't. any idea's


The 2 filament on the LH Front turn signal is most likely burned out, ...........or the ground to it, & the entire socket needs replaced. Caution lights, send signals to ALL FRONT & REAR lights. All turn signal lights must be in working order, as it is a "pulsating" currect surge sent to the bulbs, LH or RH, depending which direction you wisk to turn. If 1 filament is broken, the circuit is incomplete, & no flash will occur. Usually you will get one light that stays on, & the front or rear missing lighting, is the one whichis the culpret.

Problem with driver side indicator light


Fast flashing is a warning that one of the bulbs is not working. if the front flasher d/side is out try changing the bulb and cleaning the terminals inside the unit.
