ALWAYS USE JACK STANDS! - Taking a short cut can cut your life short.


Passenger Side Front turn signal

 

The bulb burns out , actually shorts out. To fix. Order new turn signal socket (rockauto was cheapest) at 19$. about 5 minutes to install.  On each side of the headlamp housing look for 1/2 inch wide 3 inch long white plastic clips. Pull up, remove clips. Remove lamp housing. Remove rubber cover, twist turn signal socket to remove.

Buick Century Odometer, gear selector not lighting, or dim

 

Buick Century 1999-2004  Have an issue where the Odometer does not light as for the gear selector too. Four resistors will burn out, as each burns out the odometer gets dimmer till all go out.

 

Fix is easy. You tube provides the instructions:

GM Electronic Gear Indicator and Tripometer Odometer Cluster

Tools

Screwdriver, Slotted and Phillips

25w Solder iron

Radio Shack -

   Obtain (4) 150 ohm resistors

   Rosin Core Solder

   De solder ribbon

------------------------------------- 

  1. Remove negative battery wire.

  2. Remove front dash ( one screw passenger side under the fuse cover rest are clips).

  3. Remove the console cluster (4 screws and a data connector)

  4. Open and remove the circuit board

  5. Locate 4 resistors right side four are under each other. They are the small circuit resistors but the ones from radio shack will work. Some will be gone, others fall off with a touch.

  6. Bend leads of new resistors, cut to size and solder in place.

  7.  Reverse order to re install

  8. Test , wow brighter then ever.

Thanks to all who post the info that I used. Nice job.

Water Pump

The water pump is up front on passenger side.  8 mm socket and 10 mm socket. A 3/8 rachet, and along big screwdriver.

 

Time 40 mins,  Cost Water pump on sale 17$ , fluid - 10$.  Dealer 275-300$

 

Only trick is the long screwdriver which is used to hold the pully. put blade between 2 of the 4 bolts, and the AC compressor.

 

Loosen petcocks till antifreeze comes out. bring up the temp to let thermostat open.  7 and 8 mm

 

Pully 81 Ft Lbs water pump 7.25 ft lbs or tight then 1/4 turn.

 

This is a perfect 8 min video of the process

 

WINDOW REGULATOR

 

 Usually the cable will break. Easy to replace.

Purchase the complete motor and track. about 75$. Pick up new trim push pins need 10. Screw Driver , and set of sockets for the bolts. The bolts are reused.

 

Remove screw on door lever, the cap in the hand hold has 2 bolts, then remove the panel, Unconnect the tweeter wire, the door lock and the window control cable. Peal back the plastic vapor barrier.

 

Black arrow show what to remove. Disconnect the wire from the motor

 

Shows the 2 bolts that act as a clamp on the glass.

 

My last visit for 60k tires the shop came back with the following prices:

 

$105 for Antifreeze Flush

$120 for Power Steering flush

$51 for air cleaner filter

 

I did it for:

$10 Antifreeze Flush

$ 10 Power Steering Flush

$ 10 for air cleaner

1 hr labor

 

Saved $273 - 30$ = $243.00


 

Savings, it's up to you.

   - Oil Change  Up to 50$ a yr

   - Air Filter 40$

   - Fluid Replace Power Steering, Transmission, Cooling - 2 yrs / 30 k 200 or more in savings.
