One of the first steps you need to take at your end to help me help you find your problem.
Check the large terminal at the Starter Motor. There should be a larger Battery Cable and a Blue Fusible Link connected on the terminal. Be sure the connection is secure and check to be sure the fusible link is not burned.
The fusible link runs from the starter to the Alternator. Check the back of the alternator to be sure the connection there is good. Make sure the fusible link is ok under the insulation, by gently pulling on the blue fuse link. If it stretches, it is bad.
If you have checked these connections and cannot find a problem, then at minimum, I will need to work with you with a 12volt test lamp.
I will need to know by your tests with the test lamp, where we have power and were we don't.
Check the items I have mentioned in this post and my previous post, and let me know what you find.
I would also need to know if the vehicle is equipped with any type of aftermarket alarm.
And does your vehicle have keyless entry and security system.
There are some wiring issues in the left front door area that can cause everything you are experiencing. This is a common problem.
There is a technical service bulletin that addresses this issue.
BULLETIN NO.: 99-T-43
ISSUE DATE: September, 1999
GROUP/SEQ. NO.: Electrical-03
CORPORATION NO.: 99-08-45-002
Remote Keyless Entry (RKE) or Security System Inoperative and/or Engine
Will Not Crank, Power Door Locks Inoperative or Intermittently
Inoperative, Power Windows Inoperative, Power Mirror Inoperative, Door
Speaker Volume Cutting Out, 1OA BODY Fuse Open or 1OA CHIME Fuse
Open (Repair Body Wiring Harness)
1996 - 1999 Saturn S-Series Sedans and Wagons
Customer may comment that on occasion, one or more of the following conditions occur:
|^||Remote keyless entry (RKE) or security system inoperative, and/or engine will not crank. (Must be equipped with RPO code AUO.) |
|^||Power door locks inoperative or intermittently inoperative. (Must be equipped with RPO code AUO.) |
|^||Power windows inoperative. (Must be equipped with RPO code A31.) |
Power mirror inoperative. (Must be equipped with RPO code D35.) Front door speaker volume cuts out intermittently.
The cause of the above conditions may be the main body to front door wire harness coming into contact with front door hinge reinforcement bracket. (Refer to illustration.)
The harness is routed into the front doors through a grommet as it enters the outer door structure. It is then routed across the front door hinge reinforcement (about 51 mm [2 in.] from end of grommet) before it is anchored by a rosebud. Depending on variation in either the manufacturing or routing of the wire harness, there is a chance that the wire harness can come into contact with hinge reinforcement bracket and chafe, causing a short to ground on one or more of the circuits listed in this bulletin.
|Circuit 294/TAN (driver's door unlock output from RKE and security system module) - Engine will not crank and RKE and security system inoperative. A short to ground on this circuit may cause internal damage to the RKE and security system module. On 1997 vehicles (up to and including VZ264043) the 10A BODY fuse may be open. On 1997 vehicles (after VZ264043), 1998, and 1999 model year vehicles, the 1OA CHIME fuse may be open. |
|^||Circuit 294/TAN (right front door lock motor), and Circuit 295/GRA (right and left front door lock motor) - Power door locks may be inoperative due to an open on the 20A LOCKS fuse. |
|^||Circuit 340/ORN, 194/WHT, 195/LT BLU (power door lock switch circuit) |
|-||Power door locks may be inoperative due to an open on the 10A BODY fuse. |
|^||Circuit 164/DK BLU, 165/BRN (left front power window motor) or Circuit 166/LT BLU, 167/TAN (right front power window motor) - Power window(s) may be inoperative due to an open on the 30A PWR CONVCE fuse. |
|^||Circuit 81/WHT, 82/LT BLU, 89/LT GRN (Passenger side power mirror) - Power mirror may be inoperative due to an open on the 1OA BODY fuse. |
|^||Circuit 2OO/LT GRN, 117/DK GRN (right front speaker) and/or Circuit 201/TAN, 118/GRA (left front speaker) - Door speaker volume cutting out. |
Even if you decide that these checks may be too much, this information will give you a heads-up when you take the vehicle to a technician for diagnosis and repair.
You should now be armed with a likely cause for your Saturn Battery,No-start and interior lighting information. Any questions, let me know.
