Default serious electrical problems!!!

im having some serious issues with my 04 wrx: i cant get my headlights to turn on, only the DRLs will light up, not the high beams or brighter low beams. my reverse lights dont work, my e brake light is on regardless of the e brakes position, and my abs light comes on and off every time i try to turn my headlights on, and whenever my engine is running, my radiator fans are blowing. my cruise control also does not work.

this is not a joke and all of these problems happened at once when i started the car this evening after having driven it twice already today. my only electrical mod is an alarm / remote start but that was installed almost a month ago with no problems whatsoever. any imput would be great.


i have to call to schedule a warranty appointment but im looking here for any possible answers.


PLEASE HELP!!!!!

There are green connectors under the dash these should NOT be plugged together. Did you do this recently?

Who installed the alarm/remote starter? A mistake that may not have been apparent upon installation could later manifest into an electrical problem (i.e. a short). If you installed it yourself, you may want to back-track your installtion to make sure eveything is connected properly. .......just throwing out ideas/possibilities.

First thing to do is check ALL the fuses in the car, especially the large main ones in the underhood fuse box. If one of these blows it will affect several circuits in the car. Should you find one of these fuses to be blown you then must find the reason because they very rarely do so.
The green diagnostic connectors under the driver side dash will cause some strange things but not what you're reporting. The only common symptom is the fans running, but if those connectors were plugged together you would also have a constantly flashing CEL (even in "run" position with the engine off). Can't hurt to check under there anyway.
There should not be a problem getting the dealer to fix this under warranty, as long as it doesn't turn out to be caused by the alarm. If it does, the alarm installer should be responsible for the cost of the repairs.

Sounds like you have a major ground issue.

Check the wires and connections for the remote start.

check the battery cables. Disconnect the remote start if you can and see if the problem goes away.

update: no improvement. things are controlling things that they shouldent even be connected to. when i attempt to turn the headlights on ( which still dont work) my speedometer drops to zero. the same thing happens when i have the headlight switch off and i try and use "flash to pass" also, when i put the car in reverse, the e brake light and the ABS light come on in the dash and they dont go off until i start to drive forward. and my radiator fans are allways on when the engine is running.

the car drives like normal and my A/C, rear defroster, and A/C fans work as they should. my appointment is set for monday. i am POSITIVE that the alarm is not the cause of this - I work at tweeter in the mobile dept and had this alarm installed by a 7 year vet in the buisness. i have had no problems with the alarm for the entire month that it was installed. now this????????

any insights would be great. any estimates of the cost to fix incase i have to front the repair cost for tweeter?

I have had a short that produced some of those problems. A simple device that hooked into the backup light had a nick on the
wire and was touching metal. However this also produced blown fuses.If it was me I would disconnect everything that plugs into the alarm and remote starter. Basically Pull the plug on it. Then check all fuses. An alarm and remote starter has access to all lot of the car wiring, which is why I would suspect it to be the cause.

In absence of any other possible cause, the only possible thing that may be causing your problems HAS to be the alarm if nothing else is different.

Check everything that is on that fused circuit so you can find the cause, otherwise this may happen again.
Which fuse box was that in?

the one inside the car. we have tested all components connected to this fuse and will continue to monitor it closely. at this point, i sincerely believe that it was just a bad fuse that prematurely blew.

My Legacy had similar problems recently. The ABS light came on when I had the headlights on. It turned out to be shorted break lamp. The type with two poles on the base of the lamp. It took the dealer 6 days to find. The most expensive lamp I have ever replaced! $250 due to my Ext. Warr. deduct.

Sounds just like my situation after my alarm and remote start install too. I have abs and brake lights coming on together even though my brake is not engage. Also the speedometer jumps around a lot. In addition, my headlight level adjustment does not work but when I try to adjust the level the brake and abs come on immediately. I will be checking all fuses tomorrow and maybe have my installer pull the alarm/remote start to see if the problem persists? Anyone have any other suggestions?

Fixed it today. The back up light fuse was bad. It caused the abs and brake light to go on. In addition it caused the speedometer to behave weird. Hope this helps others with the same problem.
