You may have to disconnect the battery and let the computer go through a "boot up". Leave it disconnected for about five minutes or more.

Replace the fan relay switch. The dealer will charge you 400 to pull the bumper off, or you can buy the part for 45 and cut the hole in the plastic near the passenger headlight assembly and replace it yourself. There are instructions for this procedure on the web somewhere. I have had this problem more than once with my 02 GC V6.

I would check the transmission fluid level and color, should be a nice clear red color. You may need to have the filter replaced. Possibly some internal transmission problem also.

How many wiring connectors plug into it ?

Its a matter of taking each component out of the picture(unplug ,if possible) one at a time and replace fuse..But before i did i would pull the fuse box far enough out to check for burnt or pinched wires behind it...Good Luck!!!!

Hi, I've not come across that particular symbol before, but anything showing a key is usually about the ignition systems. Since it's not starting, my guess would be that your key isn't disarming the immobiliser.? Have you got another key for that vehicle which you could try instead.? Best of luck.

the lights began flashing intermittently on and off ???? . Wouldn't be a relay problem , a stuck relay the light's would be on all the time , wouldn't be able to shut them off . I would think a control module or secruity system . The BCM - body control module controls the lights . The Headlamp switch is a input to the BCM , the BCM does energize relays to turn on the lights . More then likely the automatic headlamp light sensor which is an input to the BCM could be the problem . Taking the vehicle to a qualified repair shop an having the BCM checked for DTC'S - diagnostic trouble codes is your best bet , Don't take it to autozone , advance etc... as they can not access these codes .

I don't understand what you mean this must be an automatic transmission what is first . If so and the transmission fluid looks OK First is drive dose the 4 wheel work So you can't drive the vehicle in forward motion . Neutral reverse and park at best can make go backwards . The good news is it dosen't sound like the tranny is shot do you have other electrical problems or it also could be a linkage problem if cable or VACUUM operated .

Got any phone charges or other electronics in the vehicle? Disconnect them and try the remote. Those can cause interference.

If you did the keyless entry programming thing and it doesn't work you need a new keyless entry module or maybe a fuse is blown...Check the fuses and go from there...

Check for a disconnect that enters the from of the door and check fuse panel to that area
