Yep. As long as every single ABS and TC fuse is pulled, he will have "normal" brakes with all the idiot lights on lol. But, it'll work.

Then somewhere between 50 and 55 the car starts bogging down and it fells like the breaks almost locks down. Then it drives normal for a few minutes and does it again. It kinda reminds me of someone pulling up a hand break. Do ya think this car may be haunted? LOL

Did you check the transmission fluid level/quality lately?

No such thing... wink

Aaron also makes a good point: Has Jimi tried the Traction button on the dash??
Applying the brakes should be the TC rather than the ABS, and deactivating the TC should let him drive it until it's repaired.

As long as Traction Control lamp is on, the system will be deactivated. Doesn't matter if the PCM commands it, or you use the switch.

Just got back in town. I'll mess with it some tomorrow and tues im running it by the dealer to get the codes checked again. Thanks for all the help, im still not giving up on her.

If they come up with the code you got earlier you'll need to know:
Is it the Pressure Switch in the Pressure Modulator Valve thats gone bad or is it a bad signal / wire to the EBTCM or a bad EBTCM.

Big difference in prices for either of the 3 possibilities based on that previous code.

Wire or connector repair is inexpensive.
EBTCM is much more expensive, can be bought used, but a bad pressure switch inside the Pressure modulator Valve will be the most expensive, But, still probably can find one used. IDK
One thing a Dealer may be able to do with the GM TECH 2 diag tool is to try and activate that switch in the Modulator Valve. I'm not sure if the tool is capable, but if any tool is, it would be that one.

Nowhere has he said that the TC lamp is on...

albertj I did check the tranny fluid. The level was fine and it was clean. The TC lamp never came on. I'll put the fuses back in before they run the codes. The first place that did the codes was a shop I ussually dont deal with. I got my money back from them. The place Im going to Tue is a Buick dealer, hopeing I'll get better results and explanations from them. I'll let you know what I find out. Thanks to all you guys for your replys and help. This is a good place to be a part of.

OK, didn't catch you'd checked fluid. just a thought... We'll see what dealer says, hopefully you get a tech who works on and likes the older cars...
