Land Rover Warning Lights, 3 amigos, TCM module ingesting water and stop Light bulb change and check 

Hello , very nice explanation ,thank you from Montreal. I hope in that in this case , my past experience may help somebody , seem to me is another leak coming from the cowl, on top of the water coming from the drain and the hole in the pillar. I got it all. .In my case , the water leak is the warp cowl that leave a space for the weather to get in the intake air of the AC. Solution. It easy to check the filter intake of the AC to see if it s wet. Pour some water on the windshield and look insipide without the filter , you will see water coming in.. My solution, Take of the warp cowl , put a piece of plastic or aluminium to cover the front part of AC intake entrance , put back another cowl and seal the top with silicone .if the véhicule sit on the sun , the cowl will warp again, but at least the top part will stick to the windshield. Hope it help ! Good luck I own a 2006 LR3 v6 since 2018

My '06 is now running great. I've shot the parts cannon at the arms, half-shafts, rear drive shaft, a used rear differential, all new brakes rotors, etc.etc. Did have some stubborn electrical faults, my alternator (original ,134K mi.) was putting out average of 13.9 amps, which everyone kept telling me was fine. But I installed a new aftermarket alternator and the faults went away! Now I'm getting 14.2 amps or so). So these systems really are as sensitive as others claim. There is one other issue; On every start up, I get a transmission fault that goes away immediately. My Gap tool shows an ignition solenoid fault. One way to know this is real is by being able to remove the key while still in drive. Was talking to my son about it and he read me a notice from LR about this and a recall...Wonder if they will still honor that recall. It's worth a phone call to find out. But must admit to some concern about letting a dealer open her up. There are a lot of monkeys out there calling themselves mechanics and I've had some bad experiences with dealers before. Also, took a chance on one of those plastic/vinyl dash covers. Bought it from some place in Texas for around $100. It fits and looks great. My dash was as bad as yours. Just follow the directions for prep and gluing...The provided silicone really did work! Looks like your clear coat has failed like mine as well on the hood and roof. Got the materials to redo it but ran out of good weather. All in all, I'm into this rig for about $4k in parts and $3k in the purchase last May. If I can get another 50 k miles without anything major it will have been a win. These 4.4L engines are a perfect match for this system in my opinion. We just got a foot of snow up here in MA. and after a long drive I noticed the LR does best in the standard paved road setting. The icy road setting seems to almost have too much traction, at least it seems this way for me. Anyway, still learning how to properly drive her. Take care Rene' hope you had good holidays.

Thanks

Thank you Rene, I've just purchased an '06 LR3. And it seems like water is going to be a life long issue. All my sunroof drain line ends,( not the tube itself just the softer end that has the integral grommet) have disintegrated. Amazingly bad choice in materials. the result was soaked carpet and submerged wiring in the lower floor wiring chases. When I get time I'll be removing that fuse panel in passenger side so as to access the last drain connector behind it. I see the connector in the hole from outside but if 3 have failed I'm sure the fourth is not long for this world. There's also a bulletin from LR about the exterior "A"pillar and guide pin holes which must be sealed and the pins on the covers broken off flush. I've decided to seal each snap base as well since the thin rubber gaskets on them don't look like they hold up well over time. This vehicle shouldn't be power washed or taken through a car wash since that is essentially a power wash. Not worth the risk... I've also heard that the AC condensate drain lines can get clogged and back up into the cabin.I've pulled the 4 seats and soaked carpeting cause its the only way to really dry the foam insulation under neath and check for damage and rust. It's a lot of effort to fix a problem that good engineering should have dealt with during the build. Oh well, those English! BTW I have a much better remedy for the drain line connectors involving copper street 90's, pex tubing and gasket maker. Don't want to revisit these issues again. I'll explain to anyone who's interested. Man! your dash looks as bad as mine. I've got one on order from a junk yard. And my clear coat has failed on the hood and roof, same color as yours. I'll be rebuilding the 3 air solenoid valves as well. I'm somewhat concerned that a bad bulb can mess up so many other issues because I found a bunch of bulbs in the rear storage ...What air shocks did you get? Knock offs or those Arnots? Big difference in $..... Anyway, There's something about these cars ... And maybe it says as much about those who are getting involved with them as it does about any design flaws... onward!

Thanks Rene! Yes Change the cowl panel that could be the culprit dripping in. I had that problem last summer and it was a corroded TCM & PCM, set me back a few thousand dollars. Glad to see this is easy to get to. Next dry day I’m in there. Oh! Stay away from the automatic car washes! That are pressure washing your whole truck! Currently I have a list of Amigos. I just changed indicator bulb and the bottom most light bulb in the rear and I can’t get that to work. Bought 2 types of bulbs, neither work so I wondering if I need to clean connectors for corrosion. So I am not at normal height and it is annoying . Also changed brake switch. That was first. Nothing changed. Then I did lights. Also a marker light needs changed. Will report back after that. I need to check my TCM again. I had to since replace the cowl again! Twice in two years! Your tips are all helpful. Today I will use my multimeter and check bulbs.

happy to see now i know what to fix on this 3 amigos

Great video. Just the one I was looking for. Love the details and explanation! Subbing

Quality video. Thanks so much!

Thanks , i will go ahead and take the TCM out ,,, great video

Great job showing how to actually remove the tcm... 🙄

hey there, great vids and very thorough, love it. any experience with the entire cluster lights going crazy? driving me insane. randomly just go on with hazards. usually resets with a quick turn off and on, but only temporarily. ive changed brake switch, cleaned tranny module, drives me insane!!! thanks in advance

How did you get the module out

I took mine out it had corrosion on the plug I took mine apart looked ok I used electronics cleaner on plug and TCM now it has caused more problems I didn't have before unbelievable now I will order new tmc but getting it program it what's going to cost me a grand I here at dealer this lr3 is a wonderful suv but WOW so sensitive on trying to fix simple things that turn in to big problems the tcm controls so many other functions like transmission faults I just had my transmission rebuilt
