What is eap rely on a 2004 Chevy trailblazer

adjustable pedal relay Adjustable Pedals System Components
The adjustable pedals system consists of the following components:
• The adjustable pedals position switch
• The driver seat module
• The adjustable pedals relay
• The adjustable pedals motor
• The brake pedal position sensor
Adjustable Pedals System Operation
The adjustable pedal system is controlled by the adjustable pedal switch or the driver seat module and operation can occur only while the transmission selector lever is in the PARK position. The adjustable pedal assembly is moved forward or backward by a motor, which is fixed to the brake pedal actuator with a drive cable to the accelerator pedal actuator. The adjustable pedal motor is operated by 2 motor control circuits from the adjustable pedal relay. In an inactive state, both of the motor control circuits are closed to the ground contacts within the relay. The relay coils may be energized by the relay control circuits from the driver seat module or the adjustable pedal switch. When a relay coil is energized, the motor control circuit is switched to the battery voltage supply contact. The adjuster motor is bi-directional and the direction of the pedal assembly travel is determined by which of the motor control circuits is closed to battery voltage, while the other remains grounded.
The driver seat module monitors the location of the adjustable pedals using the brake pedal position sensor. The brake pedal position sensor is supplied with 5-volt reference and ground circuits from the driver seat module. The position sensor signal circuit is referenced from ground within the driver seat module. The signal voltage monitored by the driver seat module ranges from 0.39-4.58 volts and is determined by the wiper location on the resistor within the position sensor. The position sensor circuit voltage level is used by the driver seat module to determine the position of the adjustable pedals when storing or recalling memory position settings.

Please help. 1994 Mercedes E320 power windows are dead.

Under the rear seat cushion on the drivers side is a control module/ relay box that operates all the windows and the sunroof for the car. To lift up the rear seat cushion there is a tab on both sides of the rear seat that you push on while lifting the seat up. Once the seat cushion is out you can find the relay housing on the driver side right near the bend. Start there since everything went out all at once. Wrecking yard is the best place to pick up another one.

Also another fuse box / relay plate is placed under bonnet in engine compartment area.

2002 mercedes c240 ,changed battery still will not start

I had the same problem. I don't know if your solution is the same as mine, but mine was a problem with the electronics in the seat adjustments. It was going to cost me about $1,000.00 to replace these. I had the seats unplugged.

Driver power seat adjustment and steering tilt not

It would appear that the relay is misfunctioning. Try swapping one from nearby and when your car won't start but your seats operate then you'll know what to do. THanks, Dana

1991 mercedes benz 300ce. When I start the car and buckle the seat belt or belts the warning buzzer comes on and off. I don't know if it is a seat belt problem or an ignition problem. I only have the car...

on the driver,s side under dash there is an audible relay called a seatbelt warnung relay. I would recommend replacing it because by just unplugging it you may experience interior lighting issues. It is a very common problem with that era of mercedes. If you remove the under dash you will be able to locate it by sound with the key on. Unplug it with the key off.
