I have this 2004 audi a4 with a 3.0 liter. Basically the problem i have is that the cooling fans are not coming on their own only when i turn on the blower inside even my ac is not working as soon as i turn on the blower fans start working. I replaced the thermostat, fan control module and coolant temperature sensor, i also checked every relay and looked good.
Anything else that i supposed to be inspecting?
Any help i will appreciate it very much
Thanks guys!!!!
