This answer is based off knowledge of my '95 skylark, take it with a grain of salt because it could be different. Should still be accurate because GM stereos differ little from the late 80's to mid 90's. (My brothers old '89 Pontiac grand am had the same setup)
I believe it has a double-din car stereo, low wattage. May or may not have a tape deck (depending on factory options and such). Should have 6x9 delco brand paper cone woofers in the back (complete with whizzer cone! lol) and similar 3x5 speakers in the front.
# Open the driver's door.
# Insert key into ignition.
# Turn the ignition switch to the ACC position and then to the LOCK position three times. (This step must be completed within 3 seconds - go as fast as yo can, or the system will not enter the programming mode.)
# Within 10 seconds, close and open the door two times.
# Turn the ignition switch to the ACC position and then to the LOCK position three times (again, do this within 3 seconds.)
# Within 10 seconds, close and open the door. Verify that the power door locks cycle once to confirm that the system is in programming mode.
# Within 20 seconds, press the LOCK button on the transmitter you are programming. Verify that the door locks cycle once.
# Within 20 seconds, press the UNLOCK button on the transmitter. Verify that the door locks cycle once to confirm that the system has accepted the transmitter's code.
# Repeat steps 7 and 8 for each transmitter to be added.
# Remove key from ignition.
The temperature settings on the rear vents are the same as the front vents on the same side of the vehicle. Ensure they are on heat, turned on, and are set to blow out the top (not toward the passenger's feet).
In the usa and Japan or if am not mistaking they have another assembly plant somewhere else. Suvs are based on the gmc envoy
After 2 days of screwing with mine here is what I found: Open the hood There are 2 clips on top of the headlamp unit. Lift them. Pull the headlamp unit away from the vehicle. In back of the head lamp you will see a small round cover. Remove that cover and you should have access to the bulbs. Disconnect the wiring harness from the bulb. Remove the headlamp bulb by turning the socket counter clockwise. Install the replacement bulb by turning it clockwise. Re-assemble the headlamp.
If you do NOT have the DIC package installed, you only need to turn the car to ON and slowly pump the accelerator five times. The oil life indicator will blink for a bit and go off for another 3-7.5k miles.
