1998 chevy Malibu electrical problem.
2.4 litre
dash lights = no
codes = no
work done prior = Air conditioner coolant.
GM tech = sf
question = My stereo went dead, checked fuses but seem to be okay.
Then found out my horn and my sunroof also don't work. What else can I
check?
SF:
With all of these things wrong, there must be a power loss somewhere.
Dont know if the sunroof is factory or not. If it is , there is no relation to
these 3 problems. If it is not, need to find out where the roof gets its power,
as this may be effecting other circuits.
Horns may ust be bad horns. Radio may just be bad radio.
Be sure to check ALL fuses with a test light to make sure power into and
out of fuses.

Problem with my 1997 Chevrolet Malibu
Work done to repair this problem = the crankshaft position sensor and harmonic balancer has been changed
GM tech = kk
question = after changing the crankshaft position sensor a code stating that the crankshaft position variation was not
learned. What does mean and what do i have to do to clear this code so that the engine light will go off?
A code saying that the catalyst efficiency below threshold bank 1. What does this mean and what do i have to do to
clear this code so that the engine light will go off.

Tech JK:
The crank position variance relearn needs to be done with a scanner. The code cannot be cleared until this procedure
is done. This needs to be done because of the crank sensor replacement.
Catalyst threshold can be caused either by a faulty Oxygen sensor, or a faulty catalytic converter. Reading live sensor
data and testing of the oxygen sensor would be needed to determine which one is faulty
