My cooling fans come on with the ignition turned on and never goes off until the car is off....no check eng. lights or anything like that is visual... is this something that has been tuned or????? A4 car

 

Any possibility a prior owner installed a fan switch or wired them to be always-on?

 

Does your check engine light work?

 

I am not seeing any toggle switches for it and it looks like it has the factory
plugs to the fans.....any other places or things to look for onlong those lines??

 

I see it as it starts then goes off (check engine light)

 

I'd put a scanner on it to see if the fans are being commanded on or there are any possible trouble codes.

 

so you can get error codes that are not seen through the instrument panel???

 

Yes, there are some, but not sure if they turn the fans on. That is why I suggest the scanner for fan command status. You have to start ruling things out somewhere...

 

The right scanner can do more than provide codes. It can read the various sensors, and the calculated engine operating parameters, allowing you to look at whether the data coming into the PCM from the sensors is correct, and whether the PCM is producing the required responses to the data.

 

Update..... no codes thrown....did find one fan running off a fusable link going into the fuse box under the hood...disconnected that and plugged reg. plug back into fan but fans didnt come on after temps reaches around 200 on gage.....any thoughts any one???

 

That may be "normal" fan operation, the stock programming doesn't turn on the primary fan until somewhere around 225 degrees, if I recall. You could try turning on the A/C, to see if the primary (LH) fan turns on.

 

No "primary/secondary" late 94 and newer. Both fans on low at 226°F, both fans on high ar 235°F.

 

Forgot all about that change.
