Found a Problem! What should I do!

gospel25514 on Thu September 27, 2007 1:11 AM User is offline

Year: 1997
Make: chevy
Model: Lumina
Engine Size: 3.1
Country of Origin: United States

I found a broken line around my battery/washer fluid container that appears to be a vacuum leading to a round container in my driverside fender wall. I have been having trouble with engine losing acceleration when the AC is on and air flow would come out the floor upon acceleration. Would this be the cause of my lack of power? Also how do you replace this line without taking fender off? It was snap completely into. Must have did it when I changed my battery. Any help would be great!

Go to any parts store and buy the little plastic hollow tubes used to join two pieces of vacuum line together and just splice them together at the break.. You can even find them in junkyard splicing winshield washer hose together where it goes up to the hood etc.. I think every car has one or two of them....

Freedoms just another word for nothing left to lose

Sounds like a hard plastic vacuum line has broken; just replace the broken part with rubber vacuum tubing. It comes in several sizes, take in a broken piece of hard plastic tubing to match it up, and it's inexpensive. Yes, on some vehicles the heating, vent, and AC flaps or "doors" are controlled by engine vacuum, so could be the cause of air flow coming out the wrong place. On my old '84 Jeep Cherokee, I had to repalce two of the little vacuum actuators because pulling a vacuum on them did not move the actuator rod.

very common on W cars-- the battery gases eat away the plastic line- make it brittle and it snaps-- then you lose your air out the vents on acceleration........................splice it and and all will be fine..............

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
