ABS light is on, on the dash. I replaced both sensors, and made certain wheel bearings are solid. I also checked the gears that the ABS reads, and they are clean... What else could be the problem?... Strangely enough, and I can not make this up, but in colder (icy) weather and rain, the ABS starts working again. During the hotter months it stops and stays off. What could cause this?

The traction control light came in and everything went haywire and then shut the car off and it won't crank or do anything then after 3 to 5 days it would crank and after a hour or so the car would go haywire again and wouldn't crank so I pulled out the switch reprogrammed the key for the immobilezer and hot wired it and it was good for about 6 months and then it started again so put in a new switch but B4 that I started checking fuses and there was a whole block of fuses out don't know why but replaced the switch I'm not a mech but I don't know what's the problem is can anyone shoot a suggestion. Not many folks know a whole lot about any of this so anything could help
