Bleeder screws , If you haven't replaced the unit you don't need to do anything with them . Don't need to have the vehicle running , just bleed the brakes normally . If you have replaced the Electro-Hydraulic Control Unit you need a factory scan tool to cycle the unit solenoids
Important:
• Use the two-person bleed procedure under the following conditions:
- Installing a new Electro-Hydraulic Control Unit (EHCU) or new Brake Pressure Modulator Valve (BPMV).
- Air is trapped in the valve body
• Do not drive the vehicle until the brake pedal feels firm.
• Do not reuse brake fluid that is used during bleeding.
• Use the vacuum, the pressure and the gravity bleeding procedures only for base brake bleeding.
Raise the vehicle in order to access the system bleed screws.
Bleed the system at the right rear wheel first.
Install a clear hose on the bleed screw.
Immerse the opposite end of the hose into a container partially filled with clean DOT 3 brake fluid.
Open the bleed screw 1/2 to one full turn.
Slowly depress the brake pedal. While the pedal is depressed to its full extent, tighten the bleed screw.
Release the brake pedal and wait 10-15 seconds for the master cylinder pistons to return to the home position.
Repeat the previous steps for the remaining wheels. The brake fluid which is present at each bleed screw should be clean and free of air.
This procedure may use more than a pint of fluid per wheel. Check the master cylinder fluid level every four to six strokes of the brake pedal in order to avoid running the system dry.
Press the brake pedal firmly and run the Scan Tool Automated Bleed Procedure. Release the brake pedal between each test.
Bleed all four wheels again using Steps 3-9. This will remove the remaining air from the brake system.
Evaluate the feel of the brake pedal before attempting to drive the vehicle.
Bleed the system as many times as necessary in order to obtain the appropriate feel of the pedal.

Yes it is safe to drive it now. But i would recheck your oil level before you drive it. As long as the oil level is where it is supposed to be, then you will be fine.

Sounds like it's your battery cables, either a bad ground cable or the positive cable. I would replace both and see if that fixes your problem. Your local auto parts store has them and that is a pretty easy job.

Check the tightness of the manifold bolts and look for evidence of a leaking gasket. If it is an injected petrol engine it could be leaking injector seals. Sounds like a vacuum problem. PS check all vacuum lines for cracks. Col

Assumming the compressor is the problem - You will need to capture the current gas and recharge the system after replacement - you will need to take it to an air-conditioning specialist first to have this done.

The bottom of the seat hooks into a hook on both sides of the seat in the front. To lock it down push the bottom to the rear of the car and push down to hook the seat down. If you lift the seat up you can see the round or square hooks and then you will know how far back you need to push it. It does have to be pushed hard to the rear to hook.

THis has happened to me in the past. My fix was to clean the throttle body. The problem began after my battery died. The computer was defaulted back to its original settings after replacing the battery. Once I cleaned the throttle body, everything was fine. This happened at about 85,000 miles.

This page should have parts and diagrams to look at. Does it have power locks? Maybe the wire is bad.

the little contact could have bent and is sitting on the ring, you may have to bend it so it only makes contact when you push on the horn pad. things should fit easily if the force it things can get bent out of their original shape and cause issues.

Changing both these items is not hard but you should really take it to an Air-conditioning specialist first - you need to capture the current refrigerant gases before removal and will need to recharge the system once they are refitted.
The procedure for an automatic should be the same as a manual.

I'm assuming that competent technicians are diagnosing this problem and they performed the preliminary visual examination of all exposed ABS wiring for damage, wire retainer problems, wires rubbing other vehicle components, have looked for contamination, debris, etc in the reluctor areas{I have seen this type problem caused by metallic dust created be brake pads worn to the steel backing being magnetically attracted to the sensors/tone wheels. This debris confused the sensor}

This problem on GM vehicles has been caused by front wheel hub/bearing issues. Any looseness or play in the front bearing causes the distance between the wheel speed sensor and the reluctor(trigger wheel) to change, which in turn changes the sensor signal enough to cause the ABS control module to engage the ABS, This frequently occurs during low speed turning. The solution is to replace the hub and bearing(which contains the sensor)assembly.
A second issue is that in some cases the permanent magnet in a sensor can lose some of its magnetic strength, which causes the sine wave of the sensor to be altered, which can also cause the random ABS engagement you describe. There is no practical test of the magnetic strength that can be performed in the field, so again the replacement of the sensor.
