Radiator fan

I did find that the passanger side fan on low I could hear... and it sounded 'healthy'. The driver side, in comparison, was maybe half the speed and... from the same vantage point... I couldn't hear it until I got under it. That said...

Just came in from doing some more diagnosing. I removed the four relays. I then jumped each of them.

Passenger side high and low speeds relays. Worked.

Driver side relays? Nothing.

Reinstalled the relays... started the car (cold)... turn on AC.

Passenger side fan high speed on.

Driver side fan. Nothing. Reach under... a few taps... starts spining low speed.

It appears that a new fan is in order... you called it..

Couple more questions...

The passenger side coming on high speed. It should be low speed. Does that sound like a resistor? Should I purchase a low mile used resistor... with the entire harness... plugs... swap it out? Should I replace the entire fan unit?

Likewise the driver side fan. Low mileage used... ~$60? New aftermarket ~$65?

WWPD?

Are you sure the fans run at low speed with the AC on? IDK for sure, but I expected them to run at high speed. Someone please chime in here to confirm.

Also, I've always had better luck with used, low-mileage OE parts than new aftermarket. If I found a low-mile OE fan for $60, I'd definitely go with it over aftermarket.

Everything I've read suggests that the fans run low when the AC is turned on. With the AC off the lows pop on at around 210... the highs kick on a little higher than that.

With my AC on... the left side is running low... and the passenger side is running high.

The other odd part is when I ran a jumper from the top vertical slot in relays 20 and 21... each seperately, and plugged the other end into the horizontal on 18 and 19... nothing. It is only when the 18 and 19 relays are plugged in does the fan work. Odd.

That's the puzzling part.

However, I do know I need to get a couple of fans. Arghhhhh.

Thanks, Pal.
