My 1999 Chevy Malibu 6cyl. (3.1L)
Dear JK: my a/c switch or (button) inside the car its little
light is always shutting off and on which shuts the a/c off. What
could it be?
JK:
Hello again. As long as when the a/c is on it blows nice and cold, that would tell me
the freon charge is good. So then you do have an a/c control head problem. Those
control heads are fairly common for the a/c light flashing, and turning off the a/c
compressor. You need to replace the control head in the dash.

Problem with my 2001 chevy malibu
Mileage = 94k
Engine size = 3.1
dash lights = service vehicle soon
codes = no codes come up with scanner
work done prior = body work after collision
work done to repair = none
tech = jk
question = the service vehicle soon light has been on since the
collision...the mechanics cannot find a code... Chevy seems to have rumors
about themselves purposely having computer input this data for the light
to come on...how do i turn the light off? Nothing needs to be done to
the car. Needed to know how to tell the computer to turn the light off
JK:
The service vehicle soon light is different then the service engine soon.
This is for a body system problem detected. Usually because of an ABS
problem, lighting problem, or a communication problem between several
different modules. Since it was after a collision, it may be that you need to
re-program the BCM to learn the new air bag module part #. If you only had
the powertrain computer (PCM) scanned, that would not reveal a code for
this light. You need to have the BCM and other modules scanned. If the
light is on, there is a code, or a bad module.
