Have a 2015 Chevy 2500

Problem is drivers side is blowing warmer than passenger side. Dual zone controls. 
Freon level checks out good. Replaced the blend door actuator for the drivers side and still no better than before. Also done a reset procedure I ran across that involved unhooking batteries and pulling certain fuses. You can see the actuator working going full turn in both directions for cold and hot. You can also see the actuator for the passenger side doing the same. The only thing i ran across somewhere and saw it once that it is possible the actuator needs to be calibrated to the truck. Anyone ever heard of that? I would assume something like that is a dealer only kinda thing? At my wits end here and hot down in TX. Any advice is definitely welcome. Thanks gang….

The fuse procedure is the calibration.  

 

Alternate Method (without Scan Tool)

Note: Do not operate any HVAC controls while the HVAC control module is calibrating as this may interrupt the process. If interrupted, improper HVAC performance will result.

  1. Ignition OFF/ Vehicle OFF.
  2. Remove the HVAC control module fuse for a minimum of 10 s.
  3. Install the HVAC control module fuse.
  4. Start the vehicle.
  5. Wait 40 s for the HVAC control module to self-calibrate.

 

Do you have the single zone manual climate, or the dual zone auto climate?  The actuator you replaced, where was it located?

Done that procedure already.

Have dual zone and the actuator i replaced is behind the radio. 

 

 

Did you at all happen to power the actuator while it was not installed to the HVAC box?  So plugged it in and tried to run it?

Yessir, done that then screwed it down in the hole and watched it actuate fully to cold side and hot side. 
 

Installed another actuator today just to eliminate maybe getting a bad one. Still the same. Also did the reset procedure again that you shot me earlier.  I’m at a loss with this thing.

      Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart?

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      OTA updates and radio still cuts out

      By Coastie05 · Posted

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      Gas Prices

      By Chuck FB · Posted

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !

      OTA updates and radio still cuts out

      By wxman13 · Posted

      Just wanted to get a idea of how many of you still have problems with your radio cutting out during the first few minutes of driving, my 2024 GMC Sierra still does this after a little over 2 years of complaining to my dealer about it, and OTA updates no longer complete, the check for updates in settings is greyed out for the second time while trying to install a update, my dealer took about a week to play around with it the first time this happened, and somehow got the check for updates to work, even though it would always show system is up to date when I knew it wasn't, now again 1 month later its greyed out again when the OTA update N25-F163BU tried to install, which ironically is the update to help with reliability of future updates.
