auto wrecker..

The top of the shaft is squared off so a wrench can fit on it.

On top motor in rear near fire wall should have a cap on it like a wheel valve stem

Engine compartment, below the RH Maxi-Fuse Block. The Blower Resister/Control Module is hidden from view by the Maxi Fuse Blocks. But they are located to the left (as you are facing the engine compartment firewall) of the Blower Motor. See attached diagram:

Your passkey system is disabling your starter. You are most likely going to have to replaced your ignition cylinder as the wires are probably broken. Common issue with buicks. Also make sure the key has the pellet and is not excessively worn. Hope this helps.

There is air trapped in your cooling system. applying vacuum to the cooling system with the engine off will evacuate the air pockets.

The security system (VATS/PassKey) is having problems, it's typical on those cars/years. It's been a nightmare for us. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my 94 Park Avenue that has the same security system.

Removal & Installation

If the vehicle is not equipped with an air bag, skip Step 1 and simply disconnect the negative battery cable. Also, disregard all instructions below related to air bags.

1. If equipped, disable the SIR system, as outlined in Section 6 of this manual.
   
2. If not already done, disconnect the negative battery cable.
   
3. Lower the steering column; be sure to properly support it.

1. Position the switch in the OFF-UNLOCKED position. With the lock cylinder removed, the rod is in LOCK when it is in the next to the uppermost detent; OFF-UNLOCKED is 2 detents from the top.
   
2. Remove both switch screws, then remove the switch assembly.
   

The whole switch assembly needs to be replaced and will require the steering wheel to be removed and the air bag to be disabled to prevent it from going off. I not sure what tools you have, but it may be best to have a shop take a look at it.

You might have a bad coolant tempurature sensor. I would also check the EGR valve. Any check engine light on?

There is only 1 flasher.Since your others work fine,both the flasher and the fuse are good.The first thing to try would be,turn on the blinkers,and jiggle the wire connector to the bulb in the bad signal around in all kinds of directions,it is not necessary to pull hard on it,and if anything is wrong within the connector,it will flash on.Also,inspect the inside where the bulb plugs in for corrosion or water or anything that shouldn't be there.Also,does the brake light in that spot work normal?Does the right side work normal also?Do the hazards work normally except for that one light?These are all related to another possible component within the whole system for all that I asked about.Greg

Look and find the end may be through the grill in the centre and bend a wire coat hanger to a hook see if you can give it a tug
