The car is coming due for the 245,000 mile service. I serviced the battery two days ago as there was some corrosion on the positive terminal. The car made two trips to town and back. Then yesterday I went to move the car and nothing. The radio is out, the touch door locks do not work, and the car will start with the key.only Is it possible I blew a fuse? I thought it was my fob that didn't work, but it does the same thing with the wife's fob.
The small wire connector that is the black wire on the positive, I replaced the connector as it was badly corroded.

I went through the fuse box in the engine compartment and I did not find any of the spade fuses burnt out (unless I missed one).
What did I overlook or where do I start?

 

So to confirm the car will start with the physical key?

 

Yes, I can open and start the car with the key.

 

check the fuse box drivers side left of driver's leg. check number 7.

 

I was not aware there was a fuse box in that location. Thank you! Hopefully, this is the easy fix.

 

Update: I checked continuity on all of the fuses in the panel below the dash. All are good. I went back and checked the fuses again for continuity and they are all good.
The radio works if you input the code.
There are no door locks or not able to start the car with the fob, only with the key.

So one has to ask, if you have electrical to all the fuses, what is left? What about the fob batteries? I checked mine and it has 6.0v. So that is not the issue.

The issue seems to be related to the fob...it has become "unpaired" so the car does not recognize it. Usually, if I service the battery or replace it, the car still recognizes the fob. So somewhere in the process, it lost the memory.

What else can it be? So how do I re-pair the two fobs I have?
Is there a thread on how to pair the fobs to the car?

 

If all fuses are fine, then I don't know.

My money is still on fuse 7. Recheck it, sometimes it's broken inside but you can't see it well. or try changing it, and see if things work, albeit for a bit. coz it will blow again.

This is usually due to a short in the one or both of the door handles. water penetration. But if you have a different condition, i'd be curious to know what that is.

Oh, and fyi, there's a fuse box on the passenger's side too.

 

On the passenger side as well? Dang, a mechanic can make a fortune on finding electrical issues. LOL
I will check that box and recheck fuse 7. I used an ohm meter and all checked good. Even removed #7 and it looked good. Can't hurt to recheck it.
I did see an article on shorted door handles.
More information as it comes...

 

Update: I can lock and unlock the doors with the fob. The doors lock and unlock from the inside with the switch. So the doors are locking. the outside contact seems to be intermittent. I can touch it and it will lock and unlock. It is not as responsive as it used to be.
Is the door handle failing?

 

This is no longer the problem you mention on top at the beginning. You said you can only turn on car with key, the radio doesn't work, etc.

So here, perhaps the door handle is failing, but it doesn't explain the other stuff. So, it's certainly not clear to me; your posts are unclear.

 

When I serviced the battery and replaced a corroded connector, everything had to be reset. I reset the navigation and the radio. One thing I learned is you can not start the car with the door open. Once the door is closed you can start the car. The door handle is still a hit and miss, but we can lock it with the fob and the key if the sensor isn't working.
Evidently problem is resolved. At the very least I learned where all of the fuses are!

 

 

the door handle is a known issue
