Regarding the seat, do you hear the motors trying to work when operating the switches? If not, then it does sound like a fuse or power not getting to them. If you do hear motors, but no movement, you need to try disconnecting the seat controller for a minute to see if that help to reset it. If not, then it may be bad.

Are you sure the headlights are not working properly? There is a DRL function that operates on the low beams at half power during daytime driving. A light sensor at the top of the windshield should turn them on full power at dusk, or you can do it manually with the switch. There is a "city light" in the high beam bulb housing that comes on with the low-beam headlights. The high beams are switched on with the stalk. If this is not working properly, maybe someone has changed the wiring on the headlights, or maybe there is a problem with the front SAM.

Also, where are you located? Please update your forum user's profile to show that (at least the country) because there are some differences in the functions around the globe.

well the guy i bought it from said it was fuze problem and the motor make no sounds i checked fuzes in cockpit and there fine the only one that was blown was number 7 fuze in the trunk of the car it was a 7.5 amp which i replace with another one of thoso red 7.5amps fuze.

Now for the headlight they where working before after i washed the car and replace number 7 fuze in the trunk, the headlight now stay in highbeams as soon as i turn on. I just checked it right now.
Also im from Katy Texas. Its the american model.

Headlights are controlled by the front SAM - they have no fuses. I suspect you have a problem there. Check the fuse panel under the hjob for water intrusion.

As for the seats, if nothing works, it may be a bad or disconnected seat controller. Check under there for any obvious problems like broken or unplugged wiring.

The passenger seat had a broken plugged i fixed yet still same problem also srs warning is on it says its defective I'm guessing its the same problem as seats not moving, now my alarm want working i change the battery on the key fob to the right cr 2025 ones but yet not working so i found out fuze 8 in the trunk is the right one so i went ahead and try to put new fuze on it which is a 7.5 amp and it blew in my hand, yea im ok luckily, but do you have an idea what could be going on?

Rudeney

Fuse 8 blowing means the ATA (alarm) siren is shot. it has an internal backup battery that dies with age and leaks and kills the circuitry. That, or road salt got to it. The ATA siren is located under the fender shroud, behind the front passenger side wheel. For now, just unplug it and replace fuse #8. The fix is to replace the siren (under $200, I think).

Awesome i went ahead and disconnected it for now & fuze went in no problem and now it works!! thanks you !!! and thanks for link much cheaper

victorbenz

So it turns out the cables wernt on ther all the way they where loose one problem down but now i need to fix the headlights there low beams not working still i recorded a video of me going through them, can i send it to you somewhere,

victorbenz

also SRS warning and light are still on the dash

Rudeney

Check the wiring inside the headlight assembly, where it attaches to the bulb sockets. The insulation on these wires can melt and cause shorts.

victorbenz

Imim on in right now... do you think that would have to do with the passanger window going down everytime i open it

victorbenz

just checked all 4 of them i think they are fine cable insulation melted but they light one of them was kinda loose from the housing but its fixed now, but still the light are on high beams no matter what

Rudeney

Passenger window issues would have nothing to do with the headlights. Maybe it just needs to be re-normalized. I'd pull fuse 22 (cabin panel) for a few minutes to reset the door controller. After that, lower the glass halfway, then pull up on the switch fully until it raises, then release, and pull up again and hold for five extra seconds.

As for the headlights, is it possible someone has messed with the wiring? If not, then it sounds liker a blown SAM.

victorbenz

should i disconnect battery before pulling fuze 22? and no it was working fine, i did open the front fuze box in the engine compartment on driver side infront of the steering wheel is that the SAM.. maybe i moved or unpugged something when i open the door? or even worse blew the dam thing. ?

victorbenz

Pulled the fuze but that didnt do anything window still going doen and if door open and i raise the window once it reaches the top it goes back down

sailorben

Window sounds like it's doing that anti-trap feature, where if it thinks it is closing on someone or something (by resistance) then it will stop and lower an few inches. Perhaps the window might recognise the full close as a trapped object

Rudeney

Fuse 22 is on the cabin panel (end of the dash, driver's side). And no need to disconnect the battery to pull it.

victorbenz

so i found out no need to disconnect the battery but it didn't do anything the window still messed up, when i close the door it sounds like something is loose.

Rudeney

Probably a broken window regulator. Remove the door panel and check it out. If tit's just the glass having come off the plastic "trolley" at the bottom, I believe there is a repair kit for that.
