I don't have a solution, but I have a 96 chevy with the SAME EXACT PROBLEM to the "t"! I noticed that you posted this clear back last summer, but if you get this I would really like to know if you figured out the problem. You can email me at rska92 at hotmail dot com. Any info would be extremely appreciated!! Thanks.

What is the C0265 error code


The ABS EBCM anti-lock brake module is failing causing problems with the ABS pump running constantly, also will drain your battery.
  1. Remove the ABS fuse to prevent ABS motor burn out.
  2. You can still drive your vehicle with the module removed.
  3. We recommend covering the exposed surface of the hydraulic control unit with aluminum foil to keep out water and dirt.
Common Failures:
  • ABS Pump Always Running
  • Codes: C0265, C0267, C0268
  • Pump Motor Circuit trouble code
  • Power Relay trouble code
  • Valve Relay Trouble code
  • Dump Valves (solenoids) trouble codes
  • No Communication
  • Intermediate power loss

My 2003 chevy silverado has abs light on , parking brake on , service 4wd message , and cruise control won't work . What schould I look for ?


I would probably have the computer scanned for ABS trouble codes.
It could be a switch or something else such as an actual problem with the abs system.

1998 Mercury Mystique heater blower motor doesn't work. Have replaced everything and checked both fuses (both good). What next?


Don't know how the ABS light would be related to the blower motor, you said you checked everything - did you check the blower motor circuit for power and ground with a meter or a test light ?
Is the resistor getting power from the relay ?

2006 trailblazer ac only blows on #5 speed. Replaced blower resistor & control panel. Also on any lower speed ip lites up i.e. abs, traction control,e-brake &seat belt?


****, you can check some more but from what I am reading your problem could be related to a faulty ignition switch. I am sending you a copy of some fixes.. you can compare to your condition..
Best of Luck to you..

2006 Chevrolet Trailblazer LS 4.2L, Vin S, Eng Cfg L6
Customer Concern: No blower motor function. AntiLock Brake System (ABS), Red Brake Warning Light (RBWL), Traction lights all on. Radio does not work. Tests/Procedures: 1. Check for battery voltage at fuses #31 and 39 in Rear Fuse Box under the rear seat.

2. If the voltage value is less than battery voltage, check the Orange wire at the 48 cavity connector located at the base of the steering column at pin D1.

3. If the voltage is low at C201 check the voltage at pin "G" of the ignition switch.


Potential Causes: Ignition Switch


2006 Chevrolet Trailblazer LS 4.2L, Vin S, Eng Cfg L6
Customer Concern: ABS, Low track light comes on intermittently. The heater blower motor quits running, 4WD not working. No communication with the ABS. If you disconnect the ABS computer and plug it back in, it may work. Tests/Procedures: 1. Test voltage at HVAC 30A, 4WD 15A, HVAC 1 10A, BRAKE 10A, TBC RUN 3A labeled fuses in the rear fuse block during the problem.

2. Inspect connector 101 38 cavity connector mounted along the underhood bussed electrical center. This harness may be routed tightly around the underhood fuse block, causing chafing or connector terminal contact that could induce any of the concerns listed.

3. Clean and secure ground G110 located on the lower left side of the engine block. Potential Causes: Damaged Circuit 300
Damaged Connector C101
Improperly Installed Engine Compartment Harness
Malfunctioning Ignition Switch

2003 expedition cruise control inoperative no cruise light on dash when buttom is pushed. All fuses in fuse box checked OK. No data stream information on cruise buttons.


Check the speed sensor at the tranny or near left front tire. Use a manual or find the location on the net. This sensor usually causes problems with the cruise control.

Abs light is on


Locate and pull the ABS pump fuse located in the power distribution center under the hood and CHECK IT TO SEE IF THE FUSE IS BAD. Basically you are looking for a fuse box with large amperage fuses and some relays. Look along the fender well in the engine compartment relatively close to the battery. It is a 60 amp fuse in most instances and should be clearly labeled "ABS" in the large fuse box with other similarly oversize fuses used for other high power subsystems. 
 All ABS systems are designed so that the solenoid valves in the ABS brake manifold are in safety "bypass" mode when powered down or when the ABS control module has been removed. You will have standard everyday power brakes no different than brakes built without the ABS system.

The ABS system will perform a self check once you exceed 5 MPH and the "ABS" and "brake" lamps should turn off. During this test, the controller runs the pump motor and briefly operates all of the valves. This ABS "self-test" is performed every time you start and drive.

EBCM is short for "Electronic Brake Control Module" It is the advanced computer than controls the electric motor pump and valves of your ABS system.  Burnout of the motor is very rare however. A MOSFET transistor in the EBCM (Electronic Brake Control Module) has failed, can cause the pump not to perform.

Pump motors generally do not fail, but when they do, the culprit is usually worn-out brushes or corroded electrical connections. In a worst-case scenario, your motor is beyond repair. It is bolted directly to the hydraulic assembly- a cast aluminum brake fluid distribution hub with 5 or 6 brake lines branching off of it and wiring harness.

I hope this helps before you get your hands to dirty. In short check all the electrical connections first. Try running a hot wire to the pump motor first to see if it runs and if it does, then it's not the motor and could be a easier fix by changing the (EBCM).

1998 Olds Cutlass- electronics sometimes possessed?


Sorry yadayada ! BCM has nothing to do with these systems . Could possibly be a ground issue or they share a power supply ! Red brake light an ABS light lit on the instrument cluster , these are probably related ! Have check for DTC'S - diagnostic trouble codes . Brake lights an HVAC blower motor have different grounds . After looking at a wiring diagram and seeing where B+ voltage comes from the ignition switch . The brake light an ABS light come on when the EBCM - electronic brake control module looses B+ voltage . I 'm just taking a guess here but it could be an igition swith problem . Take it an have it checked , Test don't guess !

EBCM


No, absolutely not, although the EBCM might possibly be the problem, it is a costly item and 95% of the time is replaced for nothing. Make sure to get the system diagnosed properly, if he can't get a reading from the diagnostic machine, check the abs (EBS) fuse(s), it (they) might be burnt. Then check for fluid level and fluid leaks in the brake system. If these are OK, get the wiring checked to the EBCM for powers, grounds, and data (diagnostics).
