The 236 encoder motor has a brake that needs to be energized to release the motor shaft. I have read that the brake cannot be energized for very long. Normally it is energized long enough for the motor to make an adjustment, then is de-energized to lock the shaft. That is how it locks itself into 4W...

Scroll down to the Chevrolet section.

The tail shaft is not directly coupled on this particular transfer case. The exploded view shows this. This is not the only transfer case that has this type of setup. The resistance of the viscous connected to the front shaft, front differential and front wheels is needed to keep from creeping. It i...

I got a bad feeling about this… So, I got a t-case from the pick-a-pull and I've just about finished swapping it in (including that bitch bottom bolt!) I was just about to start bolting in the front driveshaft when I noticed it spun freely. I'm pretty sure it's NOT supposed to do that, and that I l...

I have done some research for you. All of the bearings listed as a replacement for the RW20-12 have an ID listed as 1.395 accept the TIMKEN 513023 which has consistently been listed as 1.3995: http://www.rockauto.com/catalog/moreinfo.php?pk=1119313&cc=1028056 I do not have in OD of the axle shaf...

Great Work! Nice job on keeping the amps low.

C0310 is Encoder Motor A/B circuit open which means your AWD should have been disabled until the code is cleared. It takes a scanner to clear or 100 ignition cycles without a problem.

Since you are sure about your measurements, do your measurements match the measurements of the SKF bearings? Width (in) 0.86 Inner Diameter (in) 1.395 Outer Diameter (in) 2.446 How did you press your bearings in the housing? Is it possible you deformed them during installation? I have done these and...

I understood, I just had the wrong type of bearing in my mind. It appears you have the right bearings. I would make sure you are going in as straight as possible. Any angle and it probably will not slide in. After that I am not sure what could be wrong. May be there is a problem with the TORRINGTON....

If it is .002 it should be a press fit. For the bearing sets at were I work we heat the bearings up to were you can't hold your hand on them(135F) and they slide right on. Not sure if this is your problem or if they are not supposed to be press fit. I do know .002 to .003 is a common press fit number.

So... just to get the best info here I will ask:

Are you saying your front blower does not work at all or are you saying your front blower does not work when you have it on AC as opposed to heat?

Have you tried slower speeds on the front control?

I do not know what year you have but on most years all the locks are wired in parallel meaning one of the locks could be causing your circuit to draw too much amps. The locks are like the windows, they will stop working from too much heat from amp draw. Then if you wait a while they will start to wo...

Keep in mind there is a motor test done by the tccm in the first couple of seconds. You have to test for 12v between the A and B terminals and not to frame ground. The A terminal/red wire has a constant 12v. The B terminal is a switched ground which should be open after the initial motor test. Norma...

It is possible that your encoder motor is being turned on somehow. Once the vehicle is started, check for 12v at the encoder plug. If you have 12v there then unplug the TCCM plug and check for 12v at terminals A anb B. lf you have 12v at A and B you TCCM is probably bad. If you are getting 12v at th...
