Just overhaul the old one. It can be cheaper that a new one.

It seems you are low in coolant. The temperature sensor has air to sense instead of liquid and temperature gauge will be low. Try to fill up with coolant but sometimes it's hard to get rid of air from the system. Have you changed the engine thermostat?
Hope it helps

The alternator is not connected to the door locks so is a separate issue. Your issue is likely because you left the windows open in the rain and water gets into the door lock buttons (switches) and this is the faulty area. Replace the door lock buttons themselves from a junk yard. the drivers side buttons will effect the passenger side one so only replace the drivers side, they usually just pop out easily, pry up gently from one end or the other.

SP205 is a splice pack , taped to the wiring harness behide the dash near the OBD connector .

My OBD will not power up ? Code reader , scan tool ????? .Pin #16 at the OBD connector should have B+ voltage .This is what supply's B+ voltage to the scan tool / code reader . What makes you think you need a computer ? The computer doesn't supply B+ voltage to that OBD port ,.Do you know where the i/p fuse box is ? You want the CIGAR/DLC /APO FRT fuse 20amp . The other wires you mention above , don't mess with those . Those are the class 2 data bus wires .Screw with those and short one out , you will never get your vehicle started . Suggets you google GM class 2 serial data bus communications .

the throttle position sensor is located on the throttle body directly across from where the throttle cable are attached. Remove the two screws holding it in place and remove the sensor.

Have you had the car diagnosed ? Need to have vehicle hooked up to professional type scan tool .Check for DTC'S - diagnostic trouble codes . Brakes & rotors have nothing to do with electronics of the Anti-lock brakes an stability an traction control systems .Bad brakes & rotors will turn on the red brake light. The brake sensors as you call them are really wheel speed sensors . There is a EBCM - electronic brake control module , wheel speed sensors ,Plus some other thing's.
This vehicle is equipped with the DBC7.4 antilock braking system.
The vehicle is equipped with the following braking systems:
?€¢
Antilock Brake System (ABS)


?€¢
Dynamic Rear Proportioning (DRP)


?€¢
Traction Control System (TCS)


?€¢
Vehicle Stability Enhancement System (VSES) (w/JL4)

The following components are involved in the operation of the above systems:
?€¢
Electronic brake control module (EBCM)--The EBCM controls the system functions and detects failures.


The EBCM contains the following components:


-
System relay--The system relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves and pump motor.


-
Brake pressure sensors--The EBCM contains 2 brake pressure sensors that monitor applied master cylinder pressure to the wheels. The EBCM uses the brake pressure inputs to enhance VSES.


-
Vent tube--The vent tube, located in the EBCM connector, is an opening to the internal cavity of the EBCM. It allows ventilation of the EBCM internals.


?€¢
Brake pressure modulator valve (BPMV)--The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.


Important: There is a rubber isolator located under the BPMV and on the mounting studs. The rubber isolators protect the BPMV and the EBCM from vehicle vibrations.


?€¢
The BPMV contains the following components:


-
Pump motor


-
Inlet valves (one per wheel)


-
Outlet valves (one per wheel)


-
Master cylinder isolation valves (one per drive wheel)


-
Prime valves (one per drive wheel)


?€¢
Wheel speed sensors (WSS)--As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses this AC signal to calculate wheel speed. The wheel speed sensors are replaceable only as part of the wheel hub and bearing assemblies.


?€¢
Traction control switch--The TCS is manually disabled or enabled using the traction control switch.


?€¢
Brake pedal position (BPP) sensor--The EBCM receives a serial data message from the body control module (BCM) to indicate that the brake pedal is applied.


?€¢
Yaw rate sensor (w/JL4)--The EBCM uses the yaw rate sensor to determine the rate of rotation along the vehicle's vertical axis. The yaw rate sensor is packaged with the lateral accelerometer as a single component.


?€¢
Lateral accelerometer (w/JL4)--The EBCM uses the lateral accelerometer to determine the sideways acceleration of the vehicle. The lateral accelerometer is packaged with the yaw rate sensor as a single component.


?€¢
Steering wheel position sensor (SWPS) (w/JL4)--The EBCM uses the SWPS as an indication of the position and rotation of the steering wheel.


This vehicle can set multiple DTC'S
DTC C0035-C0052 DTC C0111-C0120 DTC C0121 DTC C0131-C0139 DTC C0163-C0165 DTC C0179 DTC C0186 or C0187 DTC C0196 DTC C0220-C0229 DTC C0241 or P0856 DTC C0242 DTC C0244 or P1689 DTC C0252 DTC C0253 or C0254 DTC C0281 or C081 DTC C0460 or C0461 DTC C0550 DTC C0561 DTC C0870 DTC C0899 DTC C0900 DTC C1100 DTC C1101
Your best bet is to take it to a qualified repair shop ! You have no idea of the complexity of your vehicle .

The door tracks are greased at the factory . By now, the grease in the tracks of your 2005 Montana has disappeared or become contaminated. Also, the rollers have become contaminated with dirt. Cleaning and regreasing of both tracks and rollers should result in a marked improvement.

The thermostat may have been installed upside down. You need a minimum of 50% antifreeze and no more than 70% antifreeze to water to prevent overheating and freeze protection. The radiator may be plugged up due to age and corrosion. If it overheats while stuck in traffic, the fan motor or coolant temperature sensor could be defective.
