So im new to all this and I have a problem with my car, I've got a 2005 Toyota corolla sport. I just installed a new headunit, 1200 watt max output amp and 2 12 inch subs, and I did everything thing like I've done before but this time my front right headlight (if your looking at the car) was not working. I hooked everything up by the book. Tomorrow morning I'm going to see if the headlight just burnt out. But if it's not that what could I have done?

Where did you take off the +12V for the head unit? At the fuse box? If so, that's where I would look.

No I just bought a wiring harness, I also grounded the head unit to the wiring harness in stead of to the body of the car. Could that have something to do with it?

It's possible. Check the bulb first though in case it's coincidence.

I agree, check the bulb first, or just buy a replacement and try it.
 
If the bulb checks out OK or the replacement doesn't work, disconnect the head unit (unplug it at the harness connector) and see what happens.
 
Also, check your fuses in the fuse box.

Mar 07, 2012 (5:38 am)

The radiator fans & a/c compressor stopped working the other day. The fuses, relays and grounds all check out. There is no loss of freon. When you select a/c on the control-head, the indicator lights but compressor does not engage. The radiator cooling fans do not come on at all. The engine almost overheated in rush-hour traffic. I can't drive this car until I resolve the cooling issue. Does anyone have any ideas?

which fuse block are you looking at? The ones controlling your problems are underhood, not in the passenger compartment. There's a 10 amp marked "37" that controls the AC compressor AND the Body Control Manual---so that's one suspect.

The fuses that I checked were the ones under the hood. I suspect the BCM is faulty because the Theft System indicator has been on constantly for the past year. Do you have any idea how much a BCM will cost to replace? I need to get this car back on the road.

Well the retail on the part is about $250 bucks, with a little bit of labor to R&R, and then it has to be programmed properly with the scan tool.
