I was driving on the freeway. I pushed "automatic" button for A/C. Instrument cluster including all indicators went blank and engine shut off. Restarted once but very rough idle and shut off as soon as I stepped on accelerator. Is reading codes P0141 and P0325. Service engine soon light had been on for two weeks prior to this happening. Accessory drive belt on A/C was snapped during this incident. I have checked all fuses I can think to check and all are okay. Fuel pump shut off is not tripped, I already tried resetting that. I am at a loss. Any suggestions?

Hello,

You have a oxygen sensor that has shorted out which can cause the engine to shut off. Bank 1 sensor 2 which is the side with the number one cylinder second one back.

Here is a guide to help you get the problem fixed:

Also before you replace the belt check to see if all of the pulleys are turning by hand (engine off).

Please let us know what happens.

Cheers, Ken

I found a blown fuse finally. It was a 10 amp fuse labeled "relay". I changed it and the car started and instrument panel works. If I try to turn on A/C, even though the belt is not on, the fuse blows and engine shuts off.
