on multiple problems the first thing to check is the grounds, you can have a different electrical lead to many circuits but they usually share a common ground,

if not repair or disloged foring object (pencil pen---comb---etc)
if ok before installing actuator plug back in harness and move selector switch

It sounds like you still have a leak somewhere, maybe it's a hose clamp that wasn't tightened or another leak. You should check the coolant level in the radiator, not the overflow bottle. If the system has a leak it won't create a vacunm to draw in the coolant from the overflow, the radiator could be very low. The sound you were hearing was air bubbles in the heater corem maybe the coolant wasn't topped off.. If the core was leaking there would be coolant dripping on the passenger's side floor.

Then you either have a faulty camshaft or crankshaft sensor.

They don't usually go bad, but your problem does point to that as a possibility. If your check engine light wont work is another sign.

Yes. That would be where to start. You may want to change the distributor cap and rotor also.

Do you mean there is no heat coming from the vents? or do you mean there is no blower motor operation? or do you mean the temperature control won't change from cold to hot?

The rear wheel cylinders may be bad. They receive the fluid to put pressure on the rear drum brakes. It is an inexpensive part and something you can easily do yourself if you have mechanical knowledge, otherwise a shop will stick it to you for the replacement. Also check the actual brake lines for any leaks.

If your talking about the blower motor, its under the hood. If you buy a delco part there will be instructions in the box. There is a plastic/rubber cover over the motor that needs to be cut with a very sharp knife. Anyway buy the delco part and you'll be able to figure it out from there. Good luck.

Yes. Have the diagnostic codes pulled, this will tell you where the faults in the system are.

It is either a fuse or your blower motor is out, not hard to change, can get a replacement at orileys, autozone, etc!

Please check your car battery before attempting again.
