Sounds like the RCDLR is bad. IE the Passenger Door Switch.

 

You can find them pretty cheap on ebay just make sure if you have TPMS you get the correct PDM RCDLR

 

PDM US RFA = Non TPMS

PDM US RFA TPM = TPMS

 

Will this post is an education in itself, thank you for posting. I will have to research some of the terms you quoted but thats ok.

 

My one fob has been inop for many years. Elderly family member tried to replace battery and the case is in pretty poor shape, so $25.00 and two replacements has that fixed.

 

I will look into switch today or tomorrow, thanks again

Didn't even know the 03 Silverado had TPMS. Thought it only started in 05 and became law in 08. Also thought the RCDLR was part of the BCM in 03, I'm confused.

You can add TPMS to the older trucks with the addition of the Correct PDM and programming. I have even removed TPMS from both the new and old body style trucks but for legal reasons I would never tell anyone how since its a safety and federally mandated after 07. To many people that want to sue for anything now days.

 

I only glanced at the thread and did not really look at what year he had. After posting I saw something in the tail end of one of the post that might be his fob being bad. I hope the new ones he ordered work.

 

As for keyless entry

 

03 up is not in the BCM its all in the PDM.

I guess I should add that when you have power door locks with key less that it does have its own calibration in the bcm. I flash BCMs off the car for plug and play and thats one of the required answered questions in sps before you can program.

If I enter the acronym PDM in the GM server search line for 2003 Silverado the only response I get is Pump driver module for a diesel truck. I'm trying to educate myself here so hang in there. Where physically is this PDM you're talking about located?

New fobs should be here Monday at the latest, amazon says Sunday via USPS......doubt that.

 

So the pic is the PDM or RCDLR or whatever it is called in the passenger door? And, needs to be programmed not plug and play if I understand correct?

 

I sure am hoping new fobs cure the issue, lowest cost fix so far plus mine nearly 15 years old anyway and one has nor worked for years.

 

thanks for posting

The PDM Is the RCDLR.

 

As for programming GM SPS does have programming for the PDM what functionality it actually gIves I have no idea. A new one may need to be programmed but I've never had a new one in my hand. I have programed used PDM's on the bench to the correct Vin the truck it was going to be replaced in but noticed no difference in my testing from donor truck to flashed vin in the PDM.

Coby7 & SPartanAUtoworx:

 

We are back in business. New fobs programmed smooth and are functioning. The retailer via Amazon sent his business card and recommended I go to their www site for programming instructions. I had Coby's instructions but thought I better check their site. Only difference is they mentioned I might have to hold the Unlock and Lock buttons for as long as 30 minutes. Not even close, less 30 seconds. Both are programmed.

 

Now off to mend the instrument cluster once material arrives.

 

Thanks for all the posts and advice, I have learned allot from both of you and your assistance has been a HUGE help.

 

SpartanAUtoworx, Appears you may have some used parts and I see you are showing ST Louis area. That being the case you are a stone throw away from me and I will retain your posts if that is correct.

Yes, I seen he has a keen interest in many truck areas. I will keep him in mind since he is not too far from me.

 

Your little video really pulled all together. A faulty fob will trigger some test equipment, but at the end of the day its a dud. Hence, the test light at the retailer reading ok when it was not :-)

 

Now to resurrect my other thread on the cluster once I remove it. Many, many moons ago I use to do some of that work on radios, but I need to refresh the technique.

 

Thanks again

Yes, surface mount is a technique alright compared to through hole.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      Towing In Loose Gravel

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
