I've spent some time on google and youtube looking for this answer, but apparently I'm the only one who experiences this issue.  My remote control and tpms arent working so I've purchased a new rcdlr from Chevrolet, but I cant seem to determine where it's located.  Someone mentioned previously it should be under the headliner?  Okay, that sucks, but lets get after it...but where?  

 

Can someone point me to the correct location, a helpful how-to link or anything of the like?

Above headliner on rear crossbar above rear glass. Passenger side. No programming required.

remove interior panels and pull down on headliner?  have any information on ways to access without damaging other components in the process?  I'm decently mechanically inclined, just havent taken apart interior on this truck.  I would imagine two rear sail panels need to be removed and then hopefully headliner will be free enough to access.  

 

I appreciate your response.

If memory serves you don't need to take both sides down. I think I just pulled the pass side panel and pull handle down. It's been about a year and a half so I could be wrong.

you are correct.  I pulled the upper panel on the passenger rearmost pillar.  I also removed the grab handle for safe measure.  Simply pull down on the headliner and there it was.  Replaced the unit, to no avail.  I still do not have remote control availability.  I'll look and see if there's an "at home" programming capability.  If not, I'll have the dealer figure this mess out when I take it in for power steering recall.  

 

Thanks for your help

Some more info if it will help.

 

Remote Control Door Lock Receiver Programming and Setup
Diagnostic Aids

The remote control door lock receiver only functions as an antenna, receiving the signals sent by the keyless entry transmitter and forwarding them to the body control module (BCM). The keyless entry software is contained wholly within the BCM.

Replace and Program ECU or Reprogram ECU

This ECU does not require SPS programming or any setup procedures.

took truck to dealer this morning.  Setup for power steering recall as well as try to get rcdlr working.  Attempting to program new rcdlr receiver/antenna module to no avail it was decided to also replace the BCM.  I made the judgement call to skip the diagnostics and replace the BCM.  This also did not work.  Will return to dealer at a later date to diag electical.  Tech checked fuses and all is well there so somewhere along the wiring we have an issue.  Not what I was hoping for.  

 

Will update in the future when a determination is made.

I have a 2014 chevy with this same issue.  Been happening on and off for a couple of years.  Keyless entry works when it wants and the TPMS goes in and out every couple of months.  

 

Any update on yours?

I have done some research on several websites of forums. At the bottom line, they all ended up with the dealers saying it got a “bad connection” somewhere a long the line, so I’m assuming that it’s got damage wires somewhere from the RDLCR to the BCM, I just haven’t figured out where it is actually damaged. I have checked  all the connections from the receiver up to the door sill front passenger and all was good, so somewhere up on the dashboard is what I’m thinking ?

I have an issue with my door locks too I have figured out it is only when it's around a certain vehicle it effects two different GM vehicles at my house so far there is no tpsm issues but the car effecting it does have a tpsm issue. Not sure if this helps but could give you something else to look at.

      Gas Prices

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.

      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

      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

      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 !
