Dl8 To Dl3 On 09 Silverado

In the excitement to buy a new truck I bought a 09 Silverado with DL8 mirrors ( heated and pwr adjust). My 05 had the DL3 and I miss the signal more than I thought I would. After reading so much over the last week I'm a bit lost. I know it has been done on earlier years but have started reading that some 09s are hard wired and some have a door module. Is there a way to tell without the TechII ? I'm only interested in the power adjust, heat and signal. NOT the power fold. Is the hard wire/door module a non issue if I don't want the power fold ? Thanks for any help !

several threads on this on the internet

first problem is you have to change the drivers side switch as it has the module built into it

second problem is you need it added to the system and the dealers will not do it if the truck was not ordered with it

third problem is I am not sure if I am remembering that correctly, late at night ready to go home from work

If you dont want the power fold, then you dont need the "switch". DL3 mirrors have 2 plugs, and the one with the heat, adjust, and signal will plug right into you "nonswitch" controller. The other plug will just tuck into the door panel. There are also factory looking aftermarkets mirrors with one plug that have the signal too for much cheaper than the factory dl3 mirrors. I bought one dl3 from ebay and then a signal lens assembly for the other side and added the wiring myself. easy peasy. If you want fold, you need the door module (which is actually the switch that has the fold button) and trim bezel that matches. New ones must be programmed, and the dealer may not cooperate. Used ones come preprogrammed, if you can find one, but you will not have the tilt feature when you put it in reverse.

One more thing - even if you want to switch to DL3 mirrors, you may not have the wiring in the doors to support doing so. Not sure which ones, if any have this already.

I don't agree with most of the replies, I did this exact modification. I simply installed the mirror glass from the signal mirror to the regular mirror housing added swapped the signal mirror harness to the regular mirror housing, and eliminated the unused wires (for the power fold and dim portion) plugged into my truck and presto. The plug for power adjust heat and signal is the same, there is an additional plug/harness for power fold and dimming.

 

This mod, should not be a big deal to do. That is only adding SIGNALS, nothing else.

Andy - I agree that this is no big deal. What do you not agree with about my replies specifically? I too swapped mirror glass from one mirror and put a dl3 mirror on the other side. My truck did not have the wiring to support the fold feature, but I do have the other features provided by the one connector that is the same. My one dl3 has a plug that is not used, and the one that I added the glass and wire to just has the one plug.

      Towing In Loose Gravel

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.

      I read through that and I won't lie, my eyes rolled at some of the quirks about how it can turn off the trailer braking for example but I can see how it could help control or even up the torque applied to the ground with each wheel in a boat ramp scenario. But of course what it can't do is increase the torque to the wheels if the need is there as it ends up being like driving the four wheel drive version of a two wheel drive ( high range that is ). So far the neighbor that ended up with the 3.0 duramax with the max tow package which meant the 3.73 gears and high range only, I think its been doing ok for what he has been towing but doubt he ventures off into the soft stuff with his holiday trailer. He may have towed his dads river boat locally with it ( he always used his 6.6 duramax before ), I'll have to ask him sometime if he got into a lack of power to the wheels situation as after all that engine produces a lot of torque at low speed once the turbo winds out a bit and I think it has the 10 speed and if so they have a pretty good first gear ratio at 4.70 I see which is vastly better than the 3 or four speed overdrive models of years ago.
