With these problems that I've encountered,I really can't complain the car has never left me stranded these were problems that were arising and I rectified them promptly. the previous owner took care of the car, so its only natural that these gremlins would hinder the performance of the car. AFTER ALL, IT IS AN '89!
The "SSE" is fully equipped the ride is amazing and smooth you really have a sense of a commanding position with this car. The gadgets in these cars will spoil you. From the digital compass to the 9way seat positions. everything is just a touch of a button away. The "SSE" came with the ground effects. Mine is all black with black mags and tan interior. the only real regrets I have with the 88-91 bonnevilles were the superchargers ---THEY NEVER CAME WITH THEM. only '92 and up, by then the body style changed.
Hello. I just wanted to ask the person whose doors locked and then they couldn't open them. My car has the same problem and I was wondering what did you do to fix the problem. I don't know whether to go to the junkyard and get new doors or go to an auto repair shop to get them fixed. If you could help me out that would be greatly appreciated.
I just bought a 1989 Bonneville SSE and was wondering if anyone could help me. I am wanting to know why the doors on 3 sides will not open. Only the passenger side will. Anyone with a similar problem could you please advise what may be the problem and what your solution was. Thank you very much. Very satisfied other than that in Indiana.
I just bought 89 SSE and its amazing. plenty of power and controls for everything. the previous owner said that the lock on the front passenger door stopped working, but he fixed it by taking the door panel off and lubricating everything really well.
I own a 1990 SSE and I love my car. I had the same problem with my 3 doors not opening. I called GM and they quoted me for parts, labour and taxes for all 4 doors at $1840.00!!! I found someone in the Hamilton, Ontario area that fixed them for me for $200 taxes inclued for each door. What a bargain! If you would like this persons name and number, please email me at catagd@hotmail.com and in the subject line put 'BONNEVILLE DOOR LOCKS'
