Having problems with your 2001 Mercury Grand Marquis ?
Air conditioner condensor appears to have a leak somewhere. Pressure holds when it has nitrogen. Pressure does not hold after it has been vacuumed. Can hear a ringing sound for a while. Have sprayed soap water on hoses, etc. cannot find leak anywhere
You can put 100psi of nitrogen in, and then go over every fitting and connection where there is an O ring.
