I suggest that you go to one of the Colorado forums and ask for help. coloradofans.com is a good one.
 
www.355nation.net is another.
 
A quick comment on your listed problems. The heater fan is usually a burned connection on the resistor block or a bad ground wire connection on the right inner fender. If it is a 2004 an AC cooling problem there is a fix posted there for the temperature sensor on the evaporator. The rough idle is usually cured by cleaning the throttle body. It could be other things like a coil pack or a valve but clean the throttle body first. The ABS problem is usually cured by tapping on the back side of the failing sensor and re-seating it back where it belongs. You can get more detailed info on these common problems at the above sites.

The only thing that GM Customer Service can do is monitor your repairs after you have taken it to a Chevrolet dealer for service. The dealer will charge you just for a diagnostic check. The forums can guide you through some of the simple fixes. They have helped me quite a bit. They have no simple answers for an electrical/computer problem which GM should be liable for. The ABS issue is quite scary. If the ABS stopped working, I can live with that. This issue give you no brakes at all. Good Luck.

Good Afternoon Marroe,
I seen your post and wanted to try to clarify my position and the ways I am able to assist you all. I'm part of a new department for General Motors that reaches out to customers via social media (including forums like this one, Facebook, and Twitter). In doing this, we're hoping to assist customers who otherwise might not contact us regarding a particular situation. In some ways, I acknowledge that my responses are perhaps limited in depth and scope. I am operating entirely from the GM-approved resources available to me, and when it comes to trouble shooting some problems an owner's manual is the only thing I can contribute from. Our approach to diagnosing concerns is that our dealerships are our eyes and ears, and that an in-person look at a vehicle is more accurate than a virtual one. We'd rather not have one representative of GM say one thing over the internet and another representative of GM say another in person at the dealership.
Some things I can help assist with are:
1) looking to see if there are any open safety recalls that you need to be alerted about
2) inform you of your warranty parameters (exact date/time of expiration, special coverages, etc)
3) investigate past service history in the event of a vehicle concern (an extensive service history record helps build a case towards GM assisting with the costs of a repair, but isn't the only determining factor)
4) helps to build up our database so that the interactions I have with you virtually are recorded for "text-mining" of customer service records; this assists with GM issuing recalls or service programs for makes and models of cars
 
I hope this helps to clarify our purposes for engaging with forum posts. Again, I appreciate this feedback. I am here to serve you all in the ways that I'm able to do so. If you have a question please feel free to address me on the forum or send me an email at SocialMediaGM.com, and I will do my best to find the answer for you, or lead you in the appropriate direction.
Sincerely,
Christina
GM Customer Service

Hi everyone,
        I purchased a 2006 Chevy Colorado about 4 years ago. About 2 years ago i first experienced the ABS fault issue. I touched the brake pedal to slow down and the vehicle veered off to the right, i corrected it in time but what had happened is the ABS activated for some reason but was only working on the right side of the vehicle. The ABS stayed activated for a few more seconds while i was trying to slow down, then it released and the ABS BRAKE FAULT message came up. I then had full control of the brakes. After shutting the truck off and restarting it the error message was gone. I took it to my local GM dealership (while i was under extended warranty) and they said that nothing was wrong. It happened a few more times over the next few months so i tried again, same result from the dealership. I then took it to Les Schwab, and they replaced about 1000 dollars worth of drums and pads. Also ever since i have had the truck there has been a pulse in the brake pedal. A few months later, same thing. So back to the dealership i went. When i purchased the truck in 2008 i bought a 5 year 100000 mile extended warranty. What i was not told in 2008 is that, that specific warranty starts with the vehicle manufactured date. So by this time my warranty was over (2 and half years and 40000 miles later). I threw a fit in the store and left never to go back, just decided i would live with the ABS FAULT problem. In the past week the problem has got very bad. Almost every time i stop it happens, this last weekend it happened at 75 mph and just about threw me off the interstate. Its been doing it daily, and is getting very annoying. Is there a solution to this Fault yet that anyone knows about, because we all know that GM will not man up and fix it. I'm sure there is no way that their design would ever have this many problems is the way they see things. Anyway long story short i hope that GM will fix this problem. But the way i was treated at the GM dealership in Twin Falls, ID i will most likely sale my truck and never buy a GM product again.

Hi Strick~
 
  How scary that must have been having the ABS problems at 75mph! Thankfully I have only had problems at low speeds. I have been keeping a log book in my truck for every time it happens and today again coming off of the highway I could hear that sound coming from somewhere under my dash and then the ABS brakes kicked in with no fault lights on the dash. I frequently travel 300 miles on the highway to my destination and really getting worried about the safety issues and wondering when Chevrolet will realize the magnitude of our problems with this issue and do something to make it right. I refuse to pay 1000.00's of dollars to have something fixed that is not the problem or continue to have it diagnosed and pay for no readings. I have to travel this week and wondering if I should just pull the ABS fuse again?? Does anyone know if that will do the trick? I have done it before and didn't seem to have any problems but unsure if that was just coincidence. I put the fuse back in to pass inspection. I am going to attempt to call Chevrolet tomorrow and see what they have to say. So sorry that we all have to deal with this and for the dealerships not even standing behind us. Be careful!">

The ABS system works by comparing the wheel rotation speeds and when it finds an anomaly (meaning wheels spinning at different speeds) it engages the ABS (The pulsing you feel in the pedal) to stop what it thinks is a wheel sliding.
 
There are several components that could cause your problem but the most common by far is the wheels sensors. Things like shoes, pads, drums, and rotors should not cause this problem.
 
I would start looking for a maladjusted sensor (meaning the sensor clearance is off because it is not seated properly) causing an occasional loss of sensor pulses.
 
If you also have traction control, an intermittent / weak sensor will also display an occasional traction fault without pressing on the brake. The traction control system uses the same sensors .
 
 Initially I would scan the ABS controller looking for errors (codes). The scan might tell you which sensor is failing. A solid sensor failure will set an ABS light after initially picking up speed past 10 mph without touching the brake. These are errors are easy to retrieve with a scan tool.
 
If that does not work, with the same scanner I would drive the vehicle with the ABS scanner attached and look at the output of each wheel sensor. One should be different than the others.
 
You could also have a bad ABS controller but those failures are rare.

strick,
 
I thought that I was reading my own post while reading yours. Talk to almost anyone that owns a colorado they can share the same issue. I was sick to my stomach to read all of the information on the internet about this problem. It seems that a lot of people replaced the hubs the sensors and everything but the truck and it still happens. If pulling the ABS fuse stops it, I may do that to mine. I would rather have no ABS than no brakes at all. Or having just one front wheel brake working and shooting you off the road. That happened to me too. Everyone just needs to report it. https://www-odi.nhtsa.dot.gov/ivoq/
 
Be careful, it scared the hell out of me.
