I have recently acquired one of my dream dailies, a Cadillac Seville STS, made in 1999. It has the BOSE audio unit, without navigation. I love the car, however what bothered me was I couldn’t play any of my own songs. I purchased one of those tape player Aux adapters, which "works” but sounds...

Hey guys I have a 05 sts 3.6 and the 3rd brake light left tag light and right reverse lamp are not working at all switched bulbs nothing but everything else works fine ie other reverse, tag and corner post break lamps. Any idea if this is a fuse or do I have a broken wire?

I currently own a 2013 Challenger RT with a 6 speed manual Barton shifter. There are the normal mods, but that's it (Barton, oil catch can, res delete). I am a UC Mgr at a Cadillac dealership, have owned many caddys and driven many Vs, but never owned one. My gripe is, if you have a "muscle"...

Hey all I purchased a 2005 cadillac sts with 210,000 miles as my first car and I've grown to regret it. Originally the only problem I found with the car was the power steering system having a leak. The original owner claimed the cause was just a loose connection and assured me it was fixed. I...

would like to clean the car up and get some better pics, pics of the inside too. The inside is tan and the leather is all in decent shape there is some wear on the steering wheel material. about 140,000 miles. No rust. It hasnt seen snow until this year and was kept in the garage most the time...

My son is having issues with his Seville STS. Door locks, and windows activating intermittently while driving. Alarm has gone off randomly while setting overnight. Trunk has opened several times on its own. I am thinking it is the body control module. He is 5 hours away, at college. I only get a...

I have a 2009 STS, recently I have encountered problems with the passengers side signal light not working. Naturally, my first thought once the signal light stopped working was to replace the bulb. I got a new bulb and the new bulb didn't work, and turns out the old bulb still worked. I then...

Hi there, for my Cadillacs I used the old Tech2 for scanning and programming. The license expired last year and now I'm thinking about alternatives for it which can do programming and/or resetting too. Read a lot on this forum about it, but things change so fast, so I would be glad to hear...

I was looking at what I would need to do if I wanted to try to supercharge my 4.6 L Northstar in a 2007 STS. I don’t really know the power capabilities and couldn’t find it out online of what these engines are rated for. I also don’t know what changes they did from the 4.4 L true STSV compared...

Anybody know where I can find some lowering springs for my 98 sts its a 4.6l rear wheel drive. Also will sts-v or even cts lowering springs fit my sts? Any help is appreciated. Thank you guys!!!

I have a 1992 Seville with the 4.9L. I love the car it’s been fairly good to me. My alternator recently went and I just received the new part. However, I’ve never replaced an alternator in my life. It appears to to be a simple fix. Right on the top of the motor and the bolts seem easily...

I took it to a mechanic and he said that it was the piston ring since I didn’t have any compression on cylinder one . Is it possible to have absolutely no pressure in cylinder one ? Or Is it a valve problem ?

Okay so I have a 2000 STS. I replaced the thermostat ,water pump, coolant temp sensor, and reservoir. It used to over heat right away but after flushing the coolant it doesn't overheat while driving. As long as under 4k it's cool, but when idling and accelerating faster than 4k it overheats. I'm...

Okay, so here is my story of the infamous water on the rear floorboard, discovery, research, repair and everything in between. I hope this helps someone out. I recently purchased a used 2008 STS V6. Great deal on it since it had a rebuilt title. (Normally I would steer clear of a car like that...

Very sadly the frame is gone so selling complete for parts 4.9 v8 runs well. Transmission was rebuilt by a Master less than 200 miles ago including machining some parts. Diamond white with beech nut interior. Located just north of washington DC/ just west of Baltimore. All Offers considered but...

I have a problem that I need help with. I searched the threads under STS starting issues but could not pick up anything pertaining to my issue. My car will not crank because of this “shift to park” message that continues to pop up. However, the car IS shifted to park. Prior to this happening...

I recently purchased a 2011 STS with AWD and backed into some snow and got stuck (front wheels were on dry pavement). I opened the front fuse panel and found that the AFS (Active Front Steering) fuse is missing--could this be the cause? Also, does anyone know what fuse should be used for...

My 05’ STS squeaked whenever turning the wheel at low speeds. I would spray silicone & red tacky grease on just about everything that moved behind the wheels & the squeaking would stop for a little while. This went on for a couple of months driving 100 or so miles per day on Interstates. Then...
