Question about 1996 Lexus ES 300

2 Answers

NUMEROUS ELECTRICAL PROBLEMS ALL AT ONCE ON '96 LEXUS ES 300-136,000 MILES

  • INTERIOR LIGHT WILL NOT WORK WHEN DOOR IS OPEN-WILL COME ON MANUALLY BUT VERY DIM. MY INSTRUMENT PANEL IS INCREASING LOSING LIGHT SO THE INTERIOR IS VERY DARK AT NIGHT.
  • ANTENNA WILL NOT GO UP OR DOWN, THE MOTOR IS RUNNING BUT NOT OPERATING THE ANTENNA
  • MASTER KEY LOCK NOT OPERATING DOORS. SOMEONE MENTIONED INSIDE ONE OF THE DOORS THE SWITCH HAD POPPED. IS THAT A SIMPLE FIX?
  • REAR WINDOW ON DRIVERS SIDE WILL NOT OPERATE FROM DRIVERS CONTROL PAD, BUT WORKS FROM THE DOOR ITSELF .
IS IT WORTH TAKING MY CAR IN FOR AN OVERALL DIAGNOSIS OR JUST ACCEPT THESE MINOR FLAWS? I WORRY THAT THESE MALFUNCTIONS WILL LEAD TO ADDITIONAL ELECTRONIC FAILURES IF NOT CORRECTED. I LOVE MY CAR AND I LOVE EVEN MORE NOT HAVING A CAR NOTE. IT RUNS GREAT, STILL GETS GOOD GAS MILEAGE, AND BURNS VERY LITTLE OIL. I HOPE WITH SOME RECOMMENDATIONS AND TLC I CAN KEEP ON TRUCKIN FOR AWHILE.

My ES300 problem is that the battery runs flat over a period of about 2 weeks of remaining idle. I have had all the fuses out looking for a drain on the electrics but nothing is found. The battery is nearly new and passes all manufacturers tests. I have a charger continuously in use to fully charge the battery but when not connected the charge lasts about 2 weeks. Most frustrating. Do you have any suggestions
Thanks, Maurice

How do i bim and brighten dash light 2002 buick lesabre


bim or DIM ? the dimmer switch ! Interior Lamps
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Door courtesy lamps
• Footwell courtesy lamps
• Instrument panel (I/P) compartment lamp
• Overhead console courtesy lamps
• Reading courtesy lamps
• Rear compartment courtesy lamp
• Roof rail courtesy lamps
• Sunshade vanity mirror lamps

Interior Lamps Dimming
This group of interior lighting includes lamps which may be dimmed. This group uses a combination of class 2 controlled illumination and incandescent lamps:
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches
For the interior lighting to be dimmed the following conditions must be met:
• A low light level has been detected by the dash integration module (DIM)
• Headlamp switch is placed in to the PARK or HEAD position
• Ignition switch is placed in the ON position
Then all class 2 displays and all incandescent back lighting will be illuminated to the level set by the instrument panel (I/P) dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all class 2 displays and all incandescent back lighting respond from minimum intensity to maximum brightness.
The DIM supplies battery positive voltage to the coil side of the PRK LP relay in the rear fuse block.
When the I/P dimmer switch is moved from MIN to MAX, then the instrument panel module (IPM), W/CJ2, or climate control panel (CCP), W/C67, applies a message to the class 2 communication circuit to the DIM. The DIM then applies a ground to the park lamp relay control circuit. This energizes the PRK LAMP relay and allows battery positive voltage to be applied through the DIMR fuse to the DIM. The DIM then illuminates the following incandescent lamps through the incandescent dimming output circuit:
• Cigar lighter lamp
• DIC Switch
• Headlamp switch
• HUD switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The DIM also applies a message to the following class 2 controlled illumination components:
• Drivers door module (DDM)
• HVAC control assembly
• IPC
• Radio
The DDM will then send a message through the simple bus interface (SBI) to the RH front door module (RFDM). The door modules will then illuminate the following components through the incandescent dimming output circuit:
• Air temperature switch
• Heated seat switches (W/KA1)
• Memory function switch (W/A45)
• Power door lock switches
• Power window switches
The ground for these components are provided from the DDM and RFDM.
The following components are grounded at G200:
• Headlamp switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

Door ajar switch problem more then likely or wiring issue . The BCM - body control module won't turn off interior light , let door lock because it think's the door is open . The door ajar switch is a input to the BCM .

The first thing would be to have it checked for DTC'S - diagnostic trouble codes . Also check with an enhanced scan tool to see if the BCM shows ajar switch data (open or closed ? Do you know about body electronics ?

How do fix the light in the shift lever console 2008 Jeep Grand Cherokee


fails in the darK.even with the dimmer on max.?

the lamps are very dim, if tried in daylight
this is normal , even with bright mode set !
super dim it is.
fix it. ?
what does that mean?, you never said what they do wrong first. there are more than one PRND +/- lighted cell.

all are dead. ?
why not say full symptoms?
there are 11 GC models which one is it.?
there are 3 transmissions.
did you scan the PCm first to see if there are DTC error with said components.?
the shift box has a computer inside
and must get commands telling it what to do (light up)
scan it , yet, get P0706 errors?
when any transmission acts funny or its lamps
we scan it first. (or look like dog chasing his tail)


if compelled to dig in here) (scans show NOTHING)
remove bezel using plastic pry rods
then bezel is off
showing this below. the shifter assembly.
you get to look carefully to see if there are lamps there
some are LED. the shifter is near $300
so.....

automatically adjusts the height of the headlight beam in
reaction to changes in vehicle pitch.
Instrument Panel Dimmer
Rotate the center potion of the lever to the extreme
bottom position to fully dim the instrument panel lights
and prevent the interior lights from illuminating when a
door is opened.
Rotate the center portion of the lever up to increase the
brightness of the instrument panel lights when the parking

Dashboard lights will go out randomly. It has done it for short periods before but it did it for 200 miles on hwy in dark.


The sensor is usually located on the top of your dashboard. You might see it if you look into your vehicle through your windshield at your dash.
I have seen( one time ) that a gps was bright enough that it caused the dash lights not to come on because the sensor thought it was light outside.
Or you could have gotten a bad sensor.

Instrument Panel Lights


Daytime headlight issue ? No , no sensor behind the front bumper . No Daytime time head lamp issue , doesn't turn on the instrument panel light's . This is more then likely a remote dimmer module problem .
Interior Lights Dimming Circuit Description (Pontiac)
When the park lights are on, battery positive voltage (B+) is applied via CKT 32 (YEL) to the remote dimmer module. The interior dimming switch in the lamp dimmer switch is a variable resistor which applies the dimming input via CKT 44 (DK GRN) to the remote dimmer module. The potentiometer in the lamp dimmer switch cannot provide enough current in order to operate the incandescent lights. The remote dimmer module amplifies the current, applying a variable voltage to the incandescent lights. As the amount of current increases, the lamps become brighter. As the amount of current decreases, the lamps become dimmer.
The radio, heater and A/C control assembly, instrument cluster, and passenger climate control each has a vacuum fluorescent (VF) display. When each module receives an input that the ignition switch is turned to the RUN position, each module activates the VF display at the full intensity. When the park lights are on, the radio receives the dimming level from an input on CKT 8 (GRY). The radio then relays this information to any other modules with VF displays. All modules with VF displays then adjust the dimming level of their VF display in order to match the level of the incandescent lamps.

No interior lights come on when doors are opened. Very dim instrument panel lights.


theres probably a switch off to the left of the steering wheel (probably some sort of wheel looking switch for the brightness)

I have a 2001 Lexus ES300 that has been fixed way too many times. The lights Check Engine and Trac Off are now on and I am out of patience. It has approx. 110000 miles and runs otherwise great. Can't...


Hi. If you find an answer to your problem with the trac off/engine light comming on way too often, please tell me so I can get my wifes 2001 es300 fixed. The dealer claims to have replaced the computer and numerous sensors on it's many trips back to the car lot. Once, it was kept for two months with the same problem comming back after 72 hours of regular use. I found, if you disconnect the battery for app. 20 seconds, then rehook it the lights on the dash go off for about 3 days. Help!!!
