The 4 relays for the fans are all the same - you can swap them to verify that it is not a relay.

If the relay change does not make a difference - then check the stage 2 part of the fan (turn the AC on).

If the stage 2 (high speed) fan works - the problem is likely the fan ballast resister on that side.

The spark plug DIY is here (you do not need to remove the read bumper).

thank you ~~ if the fan ballast resister~ how to fix it....

if i change the spark plug...do i need change the ignition wires or other parts~

thank you very much ~~

If it is the fan blast resister - then you cut the wires on the old one and solder or use watertight crimps when installing the new resister.

Unless your coil packs are cracked or the electrical connectors are damaged (see the DIY) you should not need to replace anything else.

In the footwell, above and to the right of the fuse compartment. There will be 4 relays in a row, all the same type. Sockets 19, 20, 21 and 22. I am going through the same thing. I removed the right radiator fan last night. With a VOM, I read 2.43 megohms resistance through both leads on the ballast resistor which explains why the fan did not work. Now I am looking at the fan itself.

Not a bad job to do, just get the car about 8-10 inches off the ground and keep track of all the different types of fasteners and locations. It took me about 1 hour to get the car in the air, remove the right wheel, wheel well liner, front bumper and get the radiator fan out. You can clean the ductwork at the same time.

Good luck
