Default Seat relays position ??

Well.. here'* my dilema.. my 97 SSEI has the center console control for the seats. All of the switches work, except for puttin the seat back ( top left switch ). It would push the seat forward when you press the button but won't go back? I"ve just taken the center module apart to find that it'* a multiplex board.. but the seat module switch works ( gives continuaty when press ) so the problem doesn't stem from there. I don't think it'* from the seat motors ( wiring ) either as it does to both front seats. Everything else works fine though, so I"m guessing it'* got to do with the seat relay.. anyone have any ideas where that is located ? ( I"m hopping I don't need to rip off the seats to find them... ) and I'm cramped enough with the seat being pushed forward already, and can't move it back... I feel like I"m driving a dinky small Import car with the seat moved forward so much .. HELP !!!

Not ure about a 97, but mine are right under the seat of my seat. Of my seat. Just behind my knees underneath. I have the recline relay going out. I know it'* the relay getting flaky, cuz both seats weird out at the same time.

Drifter,
I just checked my 97 service manual. It only shows switch, wiring, and motor. The switch determines which wire gets + and which wire gets - depending on which way you are pushing the buttons.
If you would like, I'll e-mail you the page with the diagnostic chart.

Yes please.. email me at [email protected] or [email protected]

hummm that'* interesting... I"m not doubtin you or anything ( unless the relay is also built into the board too ). But I was looking at the seat control module when I have it apart, and would've had to have 40 wires or so if it was just + - .. and didn't see that many wires coming out of the board or the connector. I am under the impression ( again could be wrong.. my Bella has proven that a few times.. hee hee.. and so did Will that alchy ) that it controls through varying the voltage, and therefore would have a relay somewhere.. but hey.. the schmetics wouldn't lie either.. hummmmm..... any help would be greatly appreciated...

Let me know what you find. Mine is controlled by a little black box under the driver'* seat. I can hear and feel the relays clicking when I select a seat control.

In the 93, the whole thing is controlled by a seat control module under the driver'* seat. Inside it,.the back, forth, and tilt functions are controlled by relays. The lumbar/side bolsters are controlled by two relays, an air pump, and multiple solenoid valves.

I would think that your problem is the switch connections, or the seat control module (one of the relays or connections inside has gone bad).

Another electrical problem! You'll have to get a test light and a good diagram of all of the wiring. I would listen for the relays, and if I don't hear them, start with the switches and move on to the seat control module. If I could hear the relay, then I would check the relay to motor connections and the motor itself.

Drifter,
I may have mislead you. If you have the AL7 seat option, there are relays. I'll need to re send you the info. The relays with the AL7 are in the Seat Control Module under LH front Seat. I'll e-mail you too.

:P HA! I was right at least ONCE!

Keep us posted. I'd like to watch this one through the fix.

:( bad news all (Siyer) my car wounded up in a ditch with 3 feet of ice water last nite on my way to see Queen Muffin of all Bonnevilles :(

I had a piece of crap Ford Explorer dinky truck in front of me last nite while it was freezing rain and snow.. he fish tailed everywhere ( and stepped on the gas too on top of it and kicked crap all over my windshield ).. it seems like he was loosing control, and as soon as I touched the brakes the ABS kicked in and I knew if I didn't do anything I'd plow into him. So needless to say I went to the oncomg traffic lane ( 2 lane highway, 1 lane per side ) which was open to avoid the ***** .. well in my efforts to do so.. I hit some black ice covered in snow.. the rear end swinged to the right.. and I counter steered to regain control.. but when the rear swinged back.. it went too far.. I tried counter steering the other way with no avail.. the car wounded up 180 degrees backwards and slid right into the ditch which happened to be surrounded my swamp. Needless to say I went swimming in the freezin cold water and had to climb out through the passenger side window. The rear driver side quater panel is dinged up pretty good and it looks like $2500 damage ( not including the extensice water damage inside the car ). So I won't be able to update you guys on the repair :( . I'm fine though.. the bonneville sure made me felt safe.. but needless to say I feel like it ruined Wacki Tamaki'* weekend and mine as we were planning on going out with a few of her friends to the bar to make some noise. I just spent 300 for a new alternator, and now I know for sure I will have to fork out another 300 for the deductible.. this sure makes this month a really really expensive one with car payment, insurance, new alternator, christmas gifts, house bills, and now the deductible for the accident. The adjuster will be looking at my car on Monday to give a better figure on how much damage and cost is taken onto my poor beauty... :( Damm Fords !!!!

Just want to thank everyone for their help though in trying to help fix my seat... have to go now... the Queen is beckoning .. hee hee... later all

I love this site because you guys always bring up car problems that only Bonneville owners can relate to. How many other cars have the kind of seat controls we do. Anyway I need some help w my my seats. The controls are in the middle console and everything works except my lumbar/massage adjustments. They dont work on either seat but they used to. What does it sound like is the prob?
