[jrollins]

i have a 2007 mazda 3 and the cooling fan runnes all the time so i changed the cooling senser and it is still running and know it is starting to overheating so now what do i do

Could be a number of things, did you buy your car used? W/ how many miles? The cooling fan could have failed or it could be a bad control module. There is likely a TSB related to this problem that your Mazda dealer knows about, I would check that out too.
