2004 Denali 4 wheel drive questions

[TollKeeper]

I have to ask... How did get a bad Wheel Speed sensor? And then the shop got a ABS Control Module?

Typically, you dont have to replace the module, unless the board is fried. Normally its just a matter of reflowing the solder points.

I do NOT have a bad wheel sensor. That is what we confirmed today. Which leaves the ABS control module. I am going to either swap it for an OH unit, or send it to the place for repair and return.

My ABS module is pn 13642514R. There are a variety of resellers online. Does anyone have advice about buying these modules.

In other news, I had success when I changed out my charcoal cannister in the fuel vent system. I can now add fuel without restriction!

Usually its just the OEM solder joints that crack and break on the abs module. Theres youtube vids of taking it apart and reflowing the solder joints on them if you have access to a soldering iron (Notice I did NOT say soldering gun).
