Slow blinking may be corrosion on a bulb base or poor connection there. Remember there are some running lights on certain H-body models that are part of the circuits so check those bulbs and holders as well.
 
As to the brake circuits blowing a fuse..., that might be related if you're getting a short to ground through corrosion on the bulb holder. Time for thorough inspection of the whole set of bulbs on the front and rear.

Looking for corrosion in the socket or on the bulb metal.
 
The bulb holders twist about a quarter turn to remove and then the bulbs push into those holders. On the rear, the taillights have little nuts on studs holding the taillights onto the body. Remove those, the taillight unit pulls out, and then twist to inspect each bulb in its holder.

Hi my name is Dan, Now I have done some leg work. By putting a test light between the neg cabel and the battery I have found that there is a maxi fuse on the firewall that say turn sig, horn, trunk when you pull that fuse the light dims down. Any ideas what is drawing the power??

#188 of 191 Traction Control problems by craddox

Apr 16, 2013 (3:48 pm)

I have an 2003 Pontiac Bonneville SSEi and I love it! I have had a weird problem though. The traction stability sensor comes on every time I begin to drive the car, followed by the Check tire pressure sensor. I know the tire pressure is fine as I check them weekly. The traction control though can kick in anytime it wants and the car thinks it is losing traction so the auto-braking comes on, pretty scary when you passing someone on the highway and all of a sudden your breaks apply themselves especially on snowy or rain soaked roads. The sensor shows the messages all the time the car is running, yet the traction control is an off and on thing, you never know when it will engage.; Luckily I don't have to do much highway driving, mostly in town where any flare ups are simple to control.
  
I should mention that the drivers seat heater stopped working about the same time all of the problems started. Any thoughts or solutions would be appreciated.

I have exact same problem, now it kills the car too, the whole DIC suts off, then car dies. GM replaced something under the seat but then called and said its still doing it, need another 500$ to diagnose it again.I took it home. It starts when i jiggle the fuse box under the hood, but doesnt stay started. DIC says everything the above guys just said. My back drivers window wont close all the way so the carpet on the floor is always damp,.not a puddle, but damp. I have a 2000 Pontiac Boneville essi. I really dont want to bring it to anyone else before I personaly find out whats wrong with it. I dont want to be told theres a magical fairy under the hood again,.lol..

Sounds llike your connector at the wheel for the wheel speed sensor is corroded and not making contact, good contact, on one of the wheels. Or you have a wheel bearing loose enough it's affecting the wheel speed sensor inside. I suggest you go to each wheel and disconnect the connector and clean and reconnect. Check each bearing for noise and for play. The in and out play should be less than 0.005 in. That's in and out along the axis of the hub, not the wobble test usually talked about on forums.
 
My first bearing that went out had given some odd signs before my tire place mentioned my hub was getting some play in it. They mentioned that the Stability System code would show in the DIC when the bearing move enough the wheel speed sensor lost count. I had parked on a slant at a garden store. And when I left the stability system was applying one brake as soon as I got up to 15 or so mph. I stopped car. Turned it off for a minute and then restarted and everything was fine. But still got an occasional Service Stability System warning. Replaced bearing with Timken from Autozone and all was fine. Then the other wheel bearing started doing the same thing ending in replacement finally.
 
If you don't find what you're looking for, you can pull the fuse for the ABS and disable it. But it is a safety feature.

I recall reading long ago that some Bonneville owner had a similar problem. He disconnected battery under seat and then went through the various fuse blocks under back seat and tightened connections including the clips that contact fuses. Same thing for the underhood relay/fuse block. He solved the problem. It may have been the actual bolts to the positive supply under the hood that helped. I can't find a stored link to that post from a few years back.
