Question about 1998 Chevrolet Express

1 Answer

On my 98 express van the driver side brake light is dim. Both lamps were changed ( 2057) and then switched, still dim on drivers side. Today I saw a van with the same problem, I thought it might be common. Any ideas?

If the light is good, and switching from side to side does nothing, then it could be as simple as a corroded power supply in the lamp base. if that's clean, or if you've cleaned it with a little baking soda and elbow grease, then i'd check voltage at the base. (use a friend to help push the pedal down. he'll think he's a mechanic then.) you should have battery voltage at the base. if not, trace the wire for suspected corrosion. if you have bat. voltage, check the ground side. good luck, electrical problems aren't fun sometimes.

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

I have a 2000 Chevy Astro Van. Sunday my husband changed the brake pads, and today none of my brake lights work. The left, right and the top center light. The signal lights, both left and right work , and...


Check the brake light switch. It is unr the drivers side of the dash and mounted on a bracket close to the brake pedal lever. There should be one wire that has power all the time and one WO that will only have power when the brake pedal is depressed. If no other wires have power with the brake pedal depressed the switch is bad. It is also possible that the switch was knocked out of adjustment. Either way a quick peak should reveal the problem Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Reverse and interior lights out, chevy express van


Fuse block under the hood. Driver's side, under the brake master cylinder. Number 18. TCB#2. Replace the fuse.

There is an under-engineered ground in the reverse circuit. If you back up with the dome lights on, it could blow that fuse. There should be some extra fuses under the cover of the fuse block.
