We had a friend that showed us how to get our car to run a check on itself and now I can't remember what it was he pushed. It was something on the left side on the fuel center. The car ran some kind of diagnostic check and showed 2 codes. Anyone know what it is I am supposed to push to get it to do that again?

Turn the key on.
On the climate control panel, press OFF and WARMER simultaneously and hold until both LED panels light up, then release. The codes will show in the Fuel Center, ending with .7.0
You can check the codes on the sticky post at the top of the 4.X engine section.
To exit the diagnostic mode, press AUTO, or turn off the key.

Thanks, will try it. Trying to see if it gives us any codes to help figure out why we keep blowing fuses when we turn on the heater/ac/defrost.

Maybe a chaffed or grounded blower motor wire or a bad blower.

I can't find where the codes are listed, have searched everywhere. My codes were E60.7.0 & E98.7.0
Please help me check these out.

You can find the OBDI (pre '96) codes here.
