Cadillac Repair: EXP 12, EXP 25, EXP 56 (Mutliple Problems), electronic leak detector, plastic tank

Question
Hi autohelp,

I have a 1999 Cadillac (Concourse) and got a couple of problems that couldn't deal with. First off, the A/C doesn't work (cool or heat). Whenever I inject Freon, the A/C works fine just for a couple of days. Then the car drains itself of Freon, the A/C stops working and I get the EXP 12 message: "LOW REFRIG - A/C OFF." What can be the problem?

I also get the EXP 56 message: "SERV STABILITY SYS." Along with the message, the Traction and ABC-LOCK signs get lightened. What is the problem here?

Finally, I get the EXP 25 message: "CHECK WASHIR FLUID." Whenever I put water in, it drains out immediately.

Thanks!

Answer
Low refrigerant means you have a leak that needs to be found using an electronic leak detector.

Service stability means that you have a fault in the suspension system

check washer fluid maens that you have a crack in the plastic tank at the bootom of the tank.
