I see you replaced the resistor twice. Did you also replace the cable that includes the connector for the resistor? Was the pins on either the resistor or the connector burned brown? GM has had so many failures of this assembly that they also offer a repair cable with a new connector. These parts are also available in the after market on sites like on Rock Auto. The cable is a simple replacement.
If the connector and resistor pins are OK, and the resistor is not burned but is indeed open, then there is a little fuse like component as part of the resistor assembly. If that is what it blowing then you are drawing too much current through the resistor assembly. This draw is caused by a bad bearing in the fan motor or a restriction dragging down the fan. If replacing the resistor is all you need to get it going again with no burned pins, then I suggest in the future that you do not use position #3. That position draws the most current through the resistor assembly. Position #4 bypasses the resistor assembly completely so 1, 2, and 4 are safe to use. Also removing and lubing the fan motor bearings or replacing the fan motor might be in order.
Here is a link to the wiring diagram for the blower motor:

Oh yes, we also have a GM customer service person monitoring over on the Colorado forum. He is as useless as the one here. It may be the same person using a different name. If not, it probably is the same department.
I can not help you on the MAF or Communications problems.
ABS / Traction Control problems are the second most common failure. This almost always is the front wheel sensor or sensors. You can usually fix those by simply tapping on the back of them with a plastic hammer to re-seat them. If that does not do it, then replacement is in order. Again after market parts are much cheaper and available for this high failure item. Check Rock Auto or your favorite auto parts store for the sensors without having to buy the whole hub like GM dealers usually sell.
"I contacted the GM rep on my blower motor resistor failure. They shipped a new resistor and cable assembly to my local dealer with instructions to install them for free. I was in and out in 30 minutes and my blower works fine now."
The real value of the whole thing would be around $40.00 retail in parts and 15 minutes labor).
I'm just dreaming I know but this is all it would take to get some real good PR for them.
I would even happier to see them do something like this with the wheel sensors and the evap vent valve. The evap vent valve is available for $15 in the after market and takes about 1/2 hour to install.
I just woke up and realized it was all just a dream. Oh well, one can dream can't they.
GM replace or fix an American Product Faulty Part?
Not going to happen. GM is losing the American "loyalist" due to their poor quality products, poor quality PR and Customer follow up, and poor "Loyalty to the loyal customer". They build them and don't back them. They throw most of their profits to business growth opportunity gambles in Opel Europe and the Asian market; waste 39 million per year on a soccer promotion, but don't replace $15 faulty American GM auto parts and simply give Americans the lip service and European sports the GM profits, Now, GM, who bought the products that paid the profits in the past to make you so BIG?
Americans!
did anything every get done about the abs fualt light issue, have a 06 i got new and this has been a pain in the [non-permissible content removed] for me,
i have a 04 Colorado 2wd. I have recently gotten the abs issue that is on the drivers side. I have actually discovered the problem with mine. The abs tone ring is magnetically held to the rear of the bearing. The ring got loose and pushed itself off the center. Finding this after replacing bearing and sensor naturally. I am trying to resolve by super gluing ring into place. Will post again if problem resolve with instructions on repair.
mileage is high but i intend on keeping it. It's a good truck but GM should stand by their product and make the truck safe.

Add me to the list. 2006 gmc canyon. New problem for me, I’ve always noticed the abs kinda makes a weird sound and sometimes comes on unnecessarily when braking.
But in the last week or so it’s gotten so bad that I think the abs system has stopped working entirely. I can hear it making noise like it’s trying to activate when I hit bumps on a rough rough going like 30-40km/h
It doesn’t seem to do anything when just driving straight on a flat road. brakes still work etc.
but it’s definitely kinda freaky because the severity of it seems to have really amped up.
Just generally makes a lot of little noises now like it trying to activate all the time, also the abs light has started coming on for the first time ever.
