1993 Pontiac Trans Sport 3.8L MIL Lamp on, A/C malfunction
The code numbers are correct, I'm pretty sure the titles are also. Vehicle is at work, I am home at 12:30 A.M., so please have mercy!! It came in for check engine light. 25 was the only one in "history codes". It was also in current codes along with the others...
