Is it difficult to change or swap out a blower resistor?

There is a relay that would control the locks I will look up where it is. But if the doors are making a grinding noise when trying to lock then sounds like you have some bad door lock actuators in the doors. It is pretty common for them to fail.The plastic gears in them wear out/strip and they become inoperable or grind. Or the actuators become weak and will unlock but wont/cannot lock. I wish I was there to hear what was going on.

no there not bad. it is located under the passenger side dash. you will see the blower motor. it is right next to it towards the fire wall. there is about 4-5 wires going to it. remove it and see if it is burned.

The door lock relays are in the left side inside fuse box.There is a lock and unlock relay they should be reversible so you can try trading places with the lock and unlock ones to see what happens.

Ok thank you, how will I be able to tell if it is burned?

The relay makes the most sense. tomorrow I will upload exactly what happens visually and verbally with cell. Thanks all.

okay, I went out and re-examined the facts . no doubt the relays got wet one works but will fall apart if I attempt to remove it they both have 5180 written on them so I think best to replace both. Passenger door is dead either way the drivers door is the one making the noise not the relays . I also noticed the open and close switch is shot on drivers door. this is from the left corner dash fuse box.

When I put my highbeams on in my car the service engine light pops on and won't turn off until the car shuts off. Nothing happens when the light comes on but it gets annoying looking at it when it does it. What could be the problem?
Thank you

If the drivers door is making the noise most likely it has a bad door lock actuator.

I tried to find the blower motor resistor, I removed the glovebox and I believe found the blower motor but I can't locate the resistor. I didn't see any wires leading anywhere. Would I need to remove the center of the console where the cd player is to find it?

Sounds like you have a water leak somewhere do you have a aftermarket alarm?

My trunk button by the steering wheel won't pop the trunk open. I checked the connection to the button and its good. If the bcm is faulty would that be a factor to it not opening?
Thank you for everything

Cant find relays local matching those numbers and whats on ebay are used garbage. fixed the door switch it was a panel issue preventing the switch from going up and down correctly but no fuses blown and the relays are corroded in place. Thanks for the schematic. all four doors will open but two front ones are probably relays and one actuator I never got a alarm with the car just two keys neither with resistors.

the resistor is under the glove box. you dont have to remove the glove box. just remove the panel under it. check and see if your fuses are ok for your trunk release button

That one probably has a pass lock sensor in ignition housings rather then a chip in the key.

In the fuse box on the D.S door that houses a big fuse for the power doors, if its blown would it be a reason why the doors won't lock and unlock with the door switch?

They still can do the pass lock with naked keys and no remotes.Did you check rock auto dot com for those relays ?I have order a lot of parts from them over the years.
