Ok first I have not helped you yet some else helped you before. So I will need some info so I can try to better help you. Now first off do you have a digital multi meter? Next what model of corrolla do you have ie a LE, CE or what and look on the drivers door and let me know if it was Canadian made or? Get back to me and we will go from there. You may need to do some tests with the multi meter so if you can't or don't feel comfortable enough doing that let me know.

No I do not want to just replace parts. Lets put you digital multi meter to work and do a couple of tests to make sure weather or not that is the problem ok. Now under the hood on the radiator support on the right (passanger) side there is a relay. This is the daytime running light relay. Let test this first. You need to check the power in this will be the red and white wire, this should be constant power if I am reading right. The red and black wire should be power when the key is on. If that is not true then it maybe the other way around the wiring diagram is not totally clear. Now your red and blue wire is power out. So if both the red and white as well as the red and black wire have power all the time then we need to look into the DRL Module. But if only one has power when the key is off but yet the red and blue wire is still sending power then we will need to unplug this relay and see if the light then turn off. If so then we will do a ohms test on the relay. This is a 4 term relay.
The ohms test will go as follows. So set you meter to ohms and check for continuity between term 1 (this is the where the red and blue wire connects to it) and term 3 (red and black wire). Then between term 1 and term 4 (red and white wire). If there is continuity between any of those then the relay has stuck closed and needs to be replaced. Get back to me and we check the DRL module next if that test good.

Ok there is also a relay behind the glove box for the daytime running lights have you checked that one? If not then please do. The light green and black wire going to it should only have power when the key is in the on possition. Let me know what you find and we will go from there.

Ok I pulled out the box saw no switch that looked like the other relay switches. There was a big bar like thing under their. Would it be in back of that. If so, do I have to take out the air bag.

If the bag has to come out does it just pop out and is it safe to pop it out. Cause I took out all of the screws that I could see. But it didn't seem to want to come out.

Do I need a tool to remove it.

Ok then lets not go there as I would rather not pull the air bag. Have you found the dtr module? Get back to me and I will look up the test for that and see what that tells us.

Ok first glad to the hear the lights are back in order. Now on your other problems thats strange. Now if I understand right the brake pedal was hard? So the tow truck driver shook the pedal and now it is fine? I would think that maybe the booster had frozen water in it or it for some reason the booster didn't equalize the pressure and vacuum so it applied itself or what. But if it happens again try to unplug the vacuum line to the booster under the hood and plug it back in and see if that fixes it and get back to me then.

Are you getting power to the passanger side light? As far as the lights, I believe it has daytime running lights. If that is the case, they will be on. Finally, the fan is designed to come on when the engine reaches a certain temp.

Try disconnecting negative battery cable for a few seconds, the relay may be stuck. Then turn lights on if problem reappears:
Replace the headlight relay in fuse box in engine compartment.
