Rad. Cooling Fan Question

[rtury]

I recently removed the A/C unit ( comp. / evp. & cond.) as well as replaced my radiator and fan switch (75 degree switch) from my 85.5 944. What I'm trying to do is utilize the A/C cooling fan ( drivers side cooling fan) to come on with the regular cooling fan so that both fans are cooling the radiator. Both motors were tested and work, however the passenger fan is the only one coming on. Couple of questions:

1. Can I wire the passengers fan switch to work both motors and if so will the load offset the motors or any other circuitry?

2. Are both fans wired separately (I understand the A/C portion) and are they controlled by temperature variation ( at one temp. one fan comes on and when the engine reaches another temp. both fans come on?

Thanks,
Bob

Bob, could you update your signature line so we know what year you have? That will make it easier to find out which wiring schematic to look at to help.

Thanks Bob. I am sorry, didn't have time to look at it last night but I'll take a look after work and see if I can figure out an easy way to do this. The question is...do you want the second fan to run on high or low speed or both? If both...depending on what?

i would also be interested in this, living in las vegas the temps rise rather quickly. runnin both fans would probly help keep the temps manageable

Not sure how relavent this is but I've wired the two fans together in one of my 924 for years. Never had a problem...

Thank you all for your help, I was able to identify the issue. Both fans operate under seperate fuses, replaced both fuses and both fans are now working as they should ( low & high speeds)

Thanks,
Bob
