Cadillac Seville / Cadillac Eldorado Forum Discussion, Major malfunctions 99 STS in Past Cadillac Vehicle Discussion; This table is used to check battery state of charge with the battery completely disconnected and idle for at least ...
So my car is having some type of ground issue. After waiting 19 days I finally went and towed it out of a shop to another more professional shop! Hopefully I will know what's exactly wrong by tomorrow morning!!
Ok was told its a bad engine mount bracket which is bending causing the ground wire on the alternator to fail, no exactly sure the details will find out in full tomorrow morning. Do know it's over a grand to fix!! My insurance is up next week too, this could be a sign!!

Re: Major malfunctions 99 STS
Sounds dubious - many other FWD models have had severely broken front center mounts, engine moves 2", and no broken wires: there should be plenty of slack in the harnesses, and there is NO motor mount in that car that could possibly cost $1,000 to replace.
Why don't you get into www.gmpartsgiant.com, your year, car, model, submodel, system and get to the parts text page for engines, mounts. At the top of the numbered descriptive text there is a "Get Info" tab - click it to get to the link for the parts illustration. Find brackets and mounts and compare prices.
Yeah I had my front one replaced and I was around $220 for labor and I think the mount was around $80 .$1000 is way to much.it can be done if u are mechanically inclined and have a decent set out tools.
Fixed all my problems!!! Except for oil pressure switch which they offered to fix for 100 dollars the light is blinking!! I going see if a oil change will stop the blinking cause I'm due or if I do have to replace going attempt to replace myself.
I added a quart of oil and the oul light doesn't come on anymore.
Here what was done to fix my problems!!
Inspected and performed diagnostic testing. Traced circuits. Inspected right front main engine ground cable, found its integrity is compromised due to a broken lower front engine mount, bracket appears to be bend as well. Broken mount is allowing engine to jump pulling on ground cable. Installed aux ground, problem still exist. Inspected ground at transmission, ok. Inspected ground at left side near transmission switch, found connector present but no ground wires. Looked for ground wires, found ground block under harness. It appears to be a replacement harness that has a lot of misrouted harnesses.
Need to Reinstall ground with aux to ground block. All conditions not present, abs/tcs light on with current c1232 code for left front speed sensor, check brake pad message on and service stability message on. Harness for both not connected to anything, possible missing connector or misrouted somewhere. Repositioned engine harness, replaced ground strap on left side engine frame rail and replaced engine mount.
Oil pressure sending unit leaking and oil light is coming on. Customer declined further work..
