1997 Chevrolet Blazer - Answered Questions & Fixed issues


i would start by investigating the fuse box for a possible blown fuse.also double check the wiring connector is fully seated on the part you have replaced

Probably not the column, it is probably the PASSLOCK system. If I remember right, the blazer/ Jimmy were a bit special. If you have a stereo shop close by that installs remote start systems, give them a call.

Where do you buy the relay and if you buy one are they all the same?

Check 20A CTSY FUSE 2 in the I/P fuse block.

None of these things are related there all separate issues.
The window problem is in the door control master switch . the abs could be a wheel speed sensor vary likely and the blower motor could be an accuator or a bad vacuum switch or a bad connection at the blower motor or the resistors .

You need either the service manual or go to Alldatadiy.com for wiring schematics.

My personal suggestion would be to go for these repair catalogs. I know this website reliable-store that i used to buy them from, and they sold online it was very good manual. Go ahead, I bet.

Bad arm bushing or bad balljoint. It could also be cause by a loose or bad wheel bearing

One of the Hubs could be staying engaged and that COULD contribute to the transmission overheating as it is constantly straining. GM had am issue at one time with the front axles on their 4X4's. The motor and harness on the axle had to be replaced, but I am not sure of the exact years of these vehicles. But sounds like a fluid issue, TOO MUCH, WRONG TYPE, OVERHEATING.

if it is a 4.3 v-6 with multiport injection ,it may be the spider unit. try putting gas into the throttle body and see if it starts. if it does than replace the fuel injection unit (spider unit)

Had an issue similar to this with a customer astro van. It was the front differential that destroyed itself. We took the front driveshaft off and he drove it like that for a while. Then sold it. So, I am not sure what happened inside that front axle, but is was locked up. As long as we took off the driveshaft, the spider gears were the only thing spinning internally. So it could be driven again.

Do you know what a splice in a wiring harness is ? Looking at a wiring diagram for the heater / A/C controller . I see S221 ,may have a break in the wire right there . Look here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model , an engine size . Under system click on HVAC , then under subsystem click on HVAC control's ,then click the search button ,then the first blue link . Scroll down to the thrid diagram. If you had factory service info. you could find the location of that splice .

May have to cut a hole in panel. Been there. Put a big sticker over the hole afterward.

There is probably a safety interlock with the brake pedal so in order to move from park the ignition must be switched on and the footbrake applied.

I suggest you read the section in the vehicle handbook and if there is such an interlock and it isn't working check the brake pedal switch function and adjustment first.

Catalytic converter could possibly be clogged. Are you getting any sulfer smell? especially when going up hills. Also if this is a vortec motor ( says VORTEC across the top of engine) they were famous for have the injector module leak in the intake.

How about to the switch , is there battery power ? Fuse #15 FWD 10amp. I/P fuse panel . BCM - body control module light's the switch indicators 2hi, 4hi,4low . Check fuse #6 10amp I/P fuse panel .
DTC 002
The transfer case encoder motor is an assembly which houses four separate channels. These channels are used to indicate to the transfer case shift control module the present gear position of the transfer case or if the transfer case is in transition between gears. The encoder motor assembly consists of an electronically conductive inner ground ring in contact with a three legged wiper arm. Each leg's length is such that it makes contact with the conductive regions of the four channels. When any leg of the wiper arm is making contact with the conductive area of any channel, the encoder provides a path to ground to the inner ground ring.
During electronic shifting, the transfer case shift control module monitors the transfer case encoder circuit for the proper operating sequence. If at any time during a shift, the encoder changes from one position to any position other than the next possible position, an error counter in the transfer case shift control module increments by four. After the counter reaches 32, the transfer case shift control module set a DTC 2, a permanent "encoder fault," and reverts to a 2HI to 4LO or a 4LO to 2HI shift pattern only. To guard against a transient, random encoder fault due to vibration, dirt, electrical noise, etc., the fault counter reduces by one each time the transfer case shift control module detects a valid encoder value. The encoder must intermittently fail 25 percent of the time for the transfer case shift control module to consider it faulty and store DTC 2.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
This step measures the voltage between the transfer case encoder circuit channels P, A, B, and C to ground.
This step tests the suspect circuit(s) for an open, short to power, or short to ground.
This step tests the encoder signal ground circuit for an open or high resistance.
DTC 2 -- Encoder Fault Step

Important: Check the transfer case shift control module for DTCs. The transfer case shift control module is not a class 2 device. DTCs are displayed on the transfer case shift control switch. Use the following four steps to obtain DTCs.
Turn OFF the ignition for 10 seconds.
Connect PIN 13 on the data link cable (DLC) to a ground. The DLC is located in the cab under the instrument panel on the driver's side.
Turn ON the ignition, with the engine OFF.
Observe the transfer case shift control switch select buttons for flashing codes.
Did you perform the Diagnostic System Check - Transfer Case?
--
YES - Go to Step 2
NO - Go to Diagnostic System Check
2
Disconnect the connector at the encoder motor.
Turn ON the ignition, with the engine OFF.
Measure the voltage between the transfer case encoder circuit channels P, A, B, and C to ground.
Does the voltage measure near the specified value?
4.8-5.1 V
YES - Go to Step 4
NO --Go to Step 3
3
Test the suspect circuit for an open, short to power, or short to ground. Refer to General Electrical Diagnosis and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
--
YES - Go to Step 8
NO - Go to Step 7
4
Turn the ignition switch OFF.
Test the encoder signal ground circuit for an open or high resistance. Refer to General Electrical Diagnosis and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
--
YES - Go to Step 8
NO - Go to Step 5
5
With a DMM at the transfer case module connector probe the encoder sign ground pin and ensure a good ground path through the module.
Did the DMM indicate a good ground path?
--
YES - Go to Step 6
NO - Go to Step 7
6
Replace the transfer case encoder motor. Refer to Motor/Encoder Replacement .
YES - Did you complete the replacement?
--
NO - Go to Step 8
--
7
Replace the transfer case shift control module. Refer to Transfer Case Shift Control Module Replacement .
YES - Did you complete the replacement?
--
NO - Go to Step 8
--
8
Clear all DTCs from memory. Refer to Diagnostic Trouble Code (DTC) Clearing .
Operate the vehicle while pressing each of the buttons on the transfer case shift control switch.
Does the DTC reset?
--
YES - Go to Step 2
NO - System OK
