Auto Air Conditioning & Heater Repair: air conditioning valves, service ports, service valves

Question
1998 grand prix; where are the air cond valves located. I know there should be a high side and low side, but only see one valve. the one valve does not fit the recharge hose. this valve is located in the middle of the car right under the windshield.

Answer
HI Cynthia, The tubings coming off the compressor sometimes have service valves.You need to locate the accumulator,it to has service ports.The accumulator is a round cylinder and might be under one of the front fender areas.look behind the head light areas on both sides.Be careful!

Good luck,davidt
