2004 Chevrolet TrailBlazer - Answered Questions & Fixed issues


Torque should be about 30-40 ft lbs. This is essentially tight by hand, no torque wrench is often used. See this how to video: Sorry the video wouldn't upload. But the shop (A1 Auto) tightened by hand and for me that's 30-40 ft lbs with open end wrenches.

You probably have a front drive splined disconnect assembly that has gone bad. This assembly engages the front differential when 4WD is selected. Below is a figure of the item, it is on the passenger side of the differential area.

If you have the two ends of the wires then they will have the same colors and you will have to put them back together. add new piece of wire if needed and make sure that they are secure. you can use plastic insulated connectors or solder them back together and use shrink tube to weather proof, soldering is the best way for a good connection to any wiring job.

many seem to be able to clean that sensor
in case you mess it up , there are plenty of good cheap sensors at the wreckers/junk yards
you were never told a fault code so go some where else and have the fault codes read as it may not have even been that sensor at fault

Not legally. If you do it illegally, you'll get a check engine light on full time.

This sounds like the A/C switch got really hot at one point and melted the coating off some wires close to it and they've fused together. You'll have to pull the A/C switch to find out, there's no being able to see under the dash without pulling a lot of stuff out to get to it.

If you have replaced the blower motor and the blower resistor, you must have a failed blower switch. Also look for indications of overheated connectors/terminals. Blower motors draw high amperage when operation on high speed, many times melting the plastic connectors housing the spade terminals carrying the heavy current load.

Remove the thick plastic panel. If I recall, there is 1 torx screw (I could be wrong), but rest are clips, just pops off.

Ignition Lock Cylinder Control Actuator
If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column as an added safety feature. The ignition lock cylinder control actuators purpose is to prevent the steering wheel from being locked when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control acutator, and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control acutator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.
