    HVAC acting weird!

    Hi, I have been having the exact same issue over the last few years, either the Heat or the A/C is set when the truck is turned off and when restarted the HVAC resets to the 74deg. After replacing the small factory battery with a red Top optima and running a much larger Alternator the HVAC...

    Broken Intake Valve from Valve Float 6.2L L92?

    You hadn't mentioned a ticking, usually a ticking noise is valve train related. Not always but that is my experience with broken valve springs and bent pushrods(not in my truck). Let me know how you make out, that is why I wrote this thread was to just see if anyone else had a similar problem. I...

    Broken Intake Valve from Valve Float 6.2L L92?

    As far as the Power Loss it was substantial, I was just getting up to speed on the Highway and it was an instant loss. There was also a very pronounced ticking noise, the only way I could keep it running was to keep the RPMs up. It would not idle at all, after we figured out that it was intake...

    how to remove 07 Denali Power Running Board Motors

    Not to be all doom and gloom but that is how mine where, it doesn't help when they get snow and ice on them either. I put a pair of cheap mud flaps on mine, I bought the cheapest flattest ones I could find and I used the 2 lower inner fender liner bolts and attached it so that the Running boards...

    how to remove 07 Denali Power Running Board Motors

    Hey no worries, yes I had the Block in Backwards. That had nothing to do with them not working, it will likely be the Motors if it is only opening or closing sporadically. When I finally got the Motors out I ended up breaking the Hinges as they are Cast Aluminum (a lot of that is because of the...

    Broken Intake Valve from Valve Float 6.2L L92?

    Thanks but it has never been over 5500prm, my Bully Dog has a Rev Limiter in it also. I do not over drive my Truck but a Truck with this power should be able to handle a bit of hard use, we are wondering(my engine builder) if it is the added weight of Vehicle as opposed to this motor in a Camaro...

    Broken Intake Valve from Valve Float 6.2L L92?

    Hi, has anyone else had this same problem, mine is an 07 Denali 6.2L and has 94000km on it. We were just getting up to speed on the highway and there was a loud ticking noise and a drop in power, then the computer started shutting stuff down and it died, I got it going and made it my friends...

    how to remove 07 Denali Power Running Board Motors

    SUCCESS, I finally have them working. After soaking the Rear Hinges in everything from Degreaser to Fluid Film, I realized that although the Hinges were moving better then when I removed them they were never going to move free enough because the motors just seemed like they would not take the...

    how to remove 07 Denali Power Running Board Motors

    I had the exact same idea about the rear hinges, yes my motors do make an attempt to go up. I went to the Dealer and ask them and I really surprised that they actually help me, they told me about an Escalade with the same problem as mine, they replaced the motors and front hinges and they would...

    how to remove 07 Denali Power Running Board Motors

    I forgot to update my own question, yes I did get the motors off. I am guessing it is because of our winters because the motors would not come out, we did end up getting them out but both front hinges broke, the Shafts were seized in the hinges and the cast aluminum broke(we also used heat). So...

    how to remove 07 Denali Power Running Board Motors

    I have an 07 Denali that has the Factory Power Running Boards, they started to slow down last summer and over the winter they struggled. So I went ahead and paid the almost $800.00can for new GM motors, so I removed all of the Bolts that hold the motor to the Bracket and I removed the Aluminum...
