I have been on other bbs and pretty much none diy guys

my abs esp light is on some how its tied to the floor heat, in other words floor heat will not turn on is there a fuse that links the two together?

I put a brake light switch in and the brake lights stayed on, i read that it could be a brake light switch, thanks for any help or any ideas

1) Welcome!

2) As far as the heater goes, there are vacuum diaphragms that open each of the heater doors. using a vacuum hand pump to find a leak is a good way to start.

3) ESP system has over 40 different possible faults.
Brake lamp switch is the cheapest & most common,
other than that you need to have the system scanned for faults.

There has to be common reasons thats goin on here, all cars a semetrical with same parts always failing, I understand the vacuum thing and the many sensor thing, but both will have a majority of the time part that fails or hose that comes off in a location,
