    A few days ago, I ran into an accident. Someone backed into my car. Since then the ac fan continously run (the smaller fan). After I stop the car , it runs until all the battery is discharge (unless I disconnect the battery). So far, I have found that it is possibly an a/c condensor fan relay problem. Does anyone know the location of this relay, it is towards the driver side close to head light,. The damage is only at that side. I tried to look for it but couldnt locate it. I dont know how it looks like and how to reach it. Can you help me locating and possibly sharing diagnostic steps of this relay. and whats its part number, please help. as i need this fixed in order to avoid taking buses

    Is that first picture your vehicle? The paint looks different in the first picture compared to the second picture - black vs green. Is this a non-US version (circular airbox)?

    That's a radiator condensor fan, have you tried just disconnecting the fan? Believe Lexus only offered those in the early years of the 100 series. I'm not sure where the relay is, I have a 2004 LX and repair manual, neither reference that.

    Might be worth getting 2 day access to techinfo.toyota.com for $15, there will be troubleshooting steps there.

    The fan relay is behind the driver side headlight, exactly where you were crashed into.
    I'm assuming it's okay to disconnect the relay for now.

    Thinking through this a bit more, I think the AC pressure switch is on that side, at least that's where it is on my 07 LC. My bumper is off and I'm in the middle of putting on a new bumper. Perhaps the switch is damaged. Believe that fan comes on at a specific temperature. Does your AC work?

    These threads might be of help.

    Thanks for all of your replies. I didnt think about disconnecting the ac fan. which I did today. Now I am able to drive the vehicle without worrying about it to drain battery to empty.

    The AC pressure switch I'm referring to is here on my 07LC.

    Thank you for sharing the picture. However, I couldnt remove the bumper to see the relay/ac fan switch/ I however, notice this piece hanging behind the front bumper and I took its picture. Is it the fan relay. the one with golden pointy end
