which relay will shut off the high speed radiator fan - 1994 90S

My car just started the constant jet engine radiator fan speed when the car is running. The water pump was changed 30k miles ago by PO. I pulled all the related fuses and relays under the hood. Jet is still going. I pulled the knee panel off and started pulling some relays. No good. Didn't pull them all because some were hard to get to. Need some help here. Not sure what to do.

I had a bad relay #214 (?) that was above the knee panel...it made my fans run even with key out.

You really have to reach up in there to get those relays/fuses out.

Allow me to consult the wiring diagrams. ;O)

The Bentley wiring diagrams say, relay 18, in the relay panel above your left knee.

Or the RH, upper most relay.

But this depends on wheather you have manual or digital climate control. Manual or automatic transmission.

Same, relay 18. The control relay differs in the relay box under the hood.

The relays in the knee panel are 3 digit relays, not two.

So are you saying the relay to pull is #18 under the hood. I allready pulled the relays under the hood that indicate they have something to do with the radiator fan and the fan kept going like a jet. The relays under the knee panel say 236, 336....??
