rebalance the tires

It's a bit of a pain, but doable with simple tools.

Loosen the front lug nuts. Jack up the van and support it on the rails just behind the front tires (not the sub frame as you need to lower that a few inches). Remove the front tires. Disconnect the sway bar link pins, and the sway bar mounting bolts. Disconnect the tie rod ends from the knuckles. Support the rear ends of the sub frame, and remove the bolts mounting it to the van. Once the sub frame bolts are out, lower the rear end of the frame. I did this by using a jack, and placing the jack stands a couple of inches below the frame. Remove the sway bar from the van. You may need to drop the rack a bit more, but be careful as the steering shaft is still connected. You should be able to get at the bolt that attaches the rack stub to the steering rod by pushing up on the boot. Remove the sub shaft bolt. Disconnect the power steering lines from the rack (at the rack). Un-bolt the rack from the sub frame, there are two bolts. The rack should be able to be removed from the drivers side of the van. I replaced the tie rod ends and the sway bar bushings when I replaced mine (new link pins are easy at this time too). The installation is reverse of removal. I measured the tie rod distances when I put the new ends on. The only change I made was that I tied the steering shaft boot down onto the rack so I could install the bolt. I couldn't push the boot up high enough to get the bolt back in. Be sure to install the new power steering line seals that should come with the rack (buy new ones if it doesn't) - the lines are different sizes so you can't mix them up. Torque everything to spec when reinstalling (the cheap Hanes manuals have what you need along with these directions!). It's easiest to install the sway bar brackets when the sub frame is hanging down. Once it's together and running, check the power steering fluid. Get an alignment immediately (I set mine up before I changed the rack).
One last bit of advice, buy the rack with the longer warranty, you don't want to do this twice.

It could be a fuse problem or it could be a defective fan motor.

After you had new tie rods and rack and pinion did you get a complete alignment on the car? Also you may want to check all 4 tires to see if they are balanced correctly.

This could be a few things, I would first start by having the front tires inspected and balanced. Unbalanced tires or a tire with a broken belt can cause both a sway and a vibration.
If the tires check out then the only components left are the Rack and the tie rods. If you already have a leak in the Rack you are not long from having to replace it.
You can test the rack and pinion yourself with the help of another person.
Have a friend sit in the driver seat to operate the wheel. (Do Not start the car)
Leave the car on the ground so that the wheels have friction against the ground. You can sit next to the passenger side, have you helper turn the wheel all the way to the left. You will now be able to see the tie rod end and Rack arm. Now have the helper turn the wheel slowly to the right. You will be looking for how much movement is in the arm and the tie rod end before the wheel tire starts to move. You might also see the tie rod end move up or down or hear a slight popping sound. Any of these is an indication that you need Tie Rod ends.
Repeat this process on the drivers side noting any movement of parts prior to the tire moving.
If all the parts are good as soon as your helper turns the wheel you should see the tire move immediately.
If you notice that you see a delayed movement from the time you turn the wheel and the time the Rack Starts moving then you will need to replace the Rack.
Thanks, and I hope this help. Dorrian

tie rod more than likely attached to the rack and pinion

if fluid is flowing out the bellows, you need to replace the steering rack assembly. There is no fluid in the area of the inner tie rod. The seal is just before the tie rod.

Steering Gear
The power rack and pinion steering gear is serviced as a power steering short rack (3L547). The front wheel spindle tie rods (3280) and tie rod ends (3A130) are serviced individually. -------------------------------------------------------------------------------------------

• The power rack and pinion steering gear incorporates quick connect fittings for the power steering pressure hose (3A719) and power steering return hose (3A713) that allow the lines to swivel. This is normal and does not indicate loose fittings.
• If the fittings leak, check to make sure they are tightened to 14-20 Nm (10-14 lb-ft). Do not overtighten.
• If the leak is not corrected, replace the fitting seals.
