Need Help With My Rav 4 Options

[glodarus]

Hi everyone, I am driving 2007 Toyota Rav 4, 2.2 D-4D. Everything was fine until the last week when I have experienced some issue with electronics. When I turn off my car, unplug the key from the ignition, my headlights stay on even though they are off. When I try to lock the car, it would not lock the car so I have to remove one of the fuses in order to turn off the headlights as well as to lock the car. Also what happens is that sometimes my headlights are able to turn off without fuse being taken out; however, air condition is staying on for unknown reason, and I still can not lock the car afterwards. In addition to all of this, my cabin fan is not working, it does not blow any air. I checked all the fuses, and they all seem fine. I took my car to local Toyota servise, and they have told me that one of the fuse contacts was not ok, and they have cleaned that fuse and everything started working fine. However, that lasted until the next stop when it started doing the same thing again. I spoke to the service again, and they said that they will order two relays and that this will solve the problem. But, to be honest with you, I am from Montenegro, and I don't think we have good toyota service here. I took my car to the professional electrician, and he told me that there is nothing wrong with the relays on my car. I am still experiencing the same problem and during these rainy days it's difficult to drive without the fan in the cabin. Thank you in advance for your help.

Welcome to the club.

It sounds like your car is picking up a stray electrical feed which is powering different devices with the ignition off. I would think your dealer is taking advice from Toyota themselves and I think they could well be right as a sticking relay would do that. I presume the car is still under warranty so would just let them go ahead and then report back if you still have a problem.

Thank you very much anchorman, I will wait for those relays and see if it will solve the problem. Thank you again!

Hi Glodarus + welcome, Anchorman knows far more about electrics + most other things than i ever will, however the only fault i have experienced on my 07 rav was when i accidently blew a fuse, This one fuse controls everything you have mentioned + you say your dealer cleaned this fuse and all was well for a short while, you could try a new fuse + cleaning up the contacts, however your rav must still be under warranty + if this is the problem your dealer must sort it out for you Good luck...

Stew,
someone recently had a problem where the fuse did not "seat" correctly when fitted if I remember rightly. Could this be a similar problem? It's very easy to get the blades of the fuse between the side of the carrier and and one of the "side" contacts rather between the contacts. Don't know, but maybe.....

Symptoms are possible match for this situation as the fuse would carry the current when clean but would probably heat up the contact because of too little conductor area. Resistance would increase and the problem would re-occur?

thank you local hero and three5, I have checked if the fuse is where it should be, and it looks like it is. I tried replacing the fuse, but did not solve the issue. I am expecting a call from local dealer this week when new relays arrive. Hopefully, this will solve it. For now, I am using "magic" cloth to remove the fog from my windshield. Best!
