newbie help
i need help in a bad way. i dont have the funds to take it into a shop so im on my own here so any help would be great.basically i have 98 ford explorer xlt 4x4. i bought it for someone and they didnt pay for it so i repo'd it and am trying to fix it so i can sell it. it has the check engine light on took it to autozone and they said it was due to codes p0420 and code p0133. what is the cause for these so i can fix it. also the driver side unlock button doesnt work how can i fix that? third the overhead compass/temp gauge doesnt display/ work how can i fix that? fourth the radio display doesnt work either (i checked the fuses allare fine) how can i fix that? any help would be great thanks again.

I don't know what the codes are but I'm surprised autozone didn't tell you what they meant. They would be more than happy to sell you the parts to repair what the codes threw. Someone is sure to chime in shortly or you could just call autozone and ask them if you can't wait.
For the unlock button, pull back the protective covering on the wiring between the door and truck, by the hinge. Look for a broken wire.
Do a search here for a fix for the radio display. It's a common problem.

p0133 upstream heated o2 sensor circuit showing slow response bank 1
good place to start is to replace the o2 sensor.
any library has aldata to look up repair on your truck and codes.
any manual also has them.
fordfuelinjection.com also has info on codes and repair.
good luck.

like i said, the o2 sensor is probably the cause.
the o2 sensor is on exhaust with wire going to it.
i think you have two.
you need to buy or borrow a manual if you intend on fixing this truck.

You should have 4 O2 sensors on that yr. If I remember right the driver side is bank 0 and the passenger is bank 1 and the front is 1 the rear is 2
So the code “p0133 upstream heated o2 sensor circuit showing slow response bank 1“is O2 bank 1,1 front right. You can buy an new O2 sensors and a O2 socket at autozone
With your overhead display the light bulb is probably burned out same with the radio
i hope this helps

It you careful you can remove the cover (not the face) from the compass to access the bulb just be careful not to break the clips they should be all plastic. As for the radio you need to remove it from the dash then you should see the light plug, twist and pull. However, Some factory radios are made by Sony this will not work with them so you would have to take the radio apart and solder in a new bulb if you find something close to the old one. I get mine at radio shack. IF YOU DON’T KNOW WHAT YOU ARE DOING DON’T DO ANY THING YOU ARE NOT WILLING TO REPLACE.
