The simple answer is as follows:
The first (red) and fourth (blue) are directly connected to the flux capacitor in the ML-29C Recipator. The second (green) is power distributing line, and connects to one of the 4 LAC sockets on the top right side. The third (brown) is a back-up power line, but is usually not active. It is also connected to one of the 4 LAC sockets and becomes active if the green line fails for 5 aggregate seconds on a 12 second timer. The fifth line (larger black one) pumps the lubricant oil throughout the device.
Look for a broken vacuum line coming out near the ac lines on the passenger side under the hood.Look for a broken vacuum line coming out near the ac lines on the passenger side under the hood.
follow the refridgerant lines from the compressor.
On the low pressure side.
where is the ac vacuum line on a 2000 impala ls> Yes I need to know about a LS
Check for a vacuum leak either under the hood or under the dash Check the operation of the vacuum actuated motors under the dash Check the operation of the selector switch Defrost is the default position for this system
The vacuum that operates the doors for an ac system is created from the vehicles engine. Check under the hood for vacuum lines that have cracked or have become disconnected to start.
The heater/ac doors are all electric. They are not vacuum controlled.
To vacuum the AC lines on a 1997 Audi Quattro, first, connect a vacuum pump to the high and low service ports of the AC system. Make sure the system is off, and then run the vacuum pump for at least 30 minutes to remove moisture and air. Afterward, close the valves on the pump and check for any leaks. Once the vacuum holds steady, you can proceed to recharge the AC system with refrigerant.
It goes into the fire wall on the pass side next to the ac lines.It goes into the fire wall on the pass side next to the ac lines.
Yes, the heater AC vent system in your 1992 Delta 88 is controlled by vacuum lines. If your air is only coming out of the defrost vents and won't switch to the vent setting, it could indicate a vacuum leak or a faulty actuator that controls the airflow direction. Check for any disconnected or damaged vacuum lines, and inspect the actuator for proper operation. Addressing these issues should help restore proper airflow functionality.
I have a 2002 Jeep Grand Cherokee Laredo that was doing the same thing. The problem was a faulty ac/heater switch. You put the switch on ac, compresser engages, lines get cold and frosty, but only hot air is coming out of the vents, because the switch has changed back to heater even though it shows ac. The cure is to have the center panel which contains the ac/heater switch, fan speed switch and temperature control replaced.
Its controlled by a vacuum hose
