Friday i started my car, and the temperature numbers flashed for about a minute, now they don't anymore, what does this mean, did it store a code? It hasn't at all since then. One other thing, my AC is warm now, probally needs recharging, im just wondering if it has been converted to R-134A.

Is there a way to scan my ECC for codes? if so i will do this at school.

Techinfo. 93 was the last year you could perform self-diagnostics through the ECC panel. Good luck.

thanks Bill! I will do this tomorrow and post the results, i think it might be Code 66 low Freon as it did this right after i tried the A/C.

Code 66 is an interesting code because it is stored in both the PCM and ECC. It has to be cleared from the PCM, not the ECC.

So many little letters, im so confused :?:
