Unhappy Turn Signal Malfunction

I'd like to, in advance, thank anyone who answers.

With that, please help!

I have a 2001 740iL with over 200,000 miles

Recently when I started my car the right turn signal came on when the turn signal arm on steering wheel was in the center/off position. It would only turn off when I put the turn signal arm in the down position. Also, to get the left turn signal to come on I have to put the turn signal arm in the top position. All controls for the turn signal arm are completely messed up. Can anyone tell me what is causing the proper sequence of the turn signal arm to be so backwards and messed up? If you tell me to look at a fuse/relay please be as specific as possible as to exactly where that is located.

Thank you

You've heard it before...LCM.

Unless the turn signal switch is actually doing it. What was the solution for your hazard light problem?

BMW told me it was the flasher button. I thought of the LCM but with the only problem being the turn signals I can't imagine that it's an $800+ fix. I would hope German technology is not that ridiculous.

Did the button fix your flasher problem?

At first yes but then it started again, and then BMW said it was a wiring problem. At the cost they gave me to fix it I declined and just disconnected it. They never mentioned anything about the LCM being the problem for that issue.

I would start by pulling the LCM connectors to check for signs of corrosion from water. The turn signal and hazard signal both work off the larger of the 3 connections.

Might try a battery nap just for kicks. Check the tail lights also for signs of corrosion around the bulb area.

MayorChuck thank you. I will try that. With as many miles as this car has I'm really trying not to dump a lot of money into it, for I'm looking for a newer car to purchase.

Can I ask with accessing the LCM do I just take off the front passenger kick plate, near door, and pull down the carpet?

Again thank you

It's behind the kick plate.

Looked after, that car should be just nicely run in. Hope you are able to fix it OK.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?

MayorChuck, thanks for the info. For mine it appears the glove box needs to be removed also to access the bolts to remove the LCM. Since it has over 200k miles I'm just gonna replace it instead of looking for water erosion. My LCM is a IV series and wanted to ask if you knew of any reputable websites I can look into for a used one. Someone mentioned I can use the III series but I am sticking with what the car currently has installed. I looked on eBay but only found this type from the United Kingdom and would rather stay in the US. Any links you can provide for a used LCM IV is very much appreciated.

Best bet is to check with members parting out a car or check with the junkyards in your area. You can just get rough with the panel at a salvage yard an pull the LCM. Keep in mind it will need to be coded to the car. It stores the vehicle mileage and works with many modules in the car. Most dealers will not mess with a used module. They want you to buy their $1500 new one, or whatever it is. These rarely need to be replaced and there is no guarantee this is your issue. But if the connections have been wet, you will need to clean the plugs anyway. With the time, money and coding expense involved, might be worth pulling it out to take a look. JMO.
