Question about Cars & Trucks
If you wait about a minute blower will start back up and run about 25 sec. This repeats over and over. Any ideas? Thanks...Phillip

The blower motor is connected to a termic switch, when the motor is fine and fuse is ok, is the switch that must be replaced.
Ensure the fuse is ok first.

check fuse #9 in the fuse box for being blown or lacking power...if there is no power to the fuse it is possible the ignition switch is bad

It sounds to me like an 'intermittently open circuit', or in plain language, when some part of the heater's circuit heats up a connection somewhere in the circuit 'opens up' stopping the flow of electricity. Then (10 minutes later?) when the circuit cools again the connection 'closes' again until warm. I would trace all the wires in that circuit from the fuse box to the blower motor (including fuse box & fuse) and look for broken or cracked insulation; make sure all connections are tight; I'd certainly check the heater's 'setting' switch (off,high, low switch) on the dash. It could also be a fusible link. This is a piece of wire somewhere in the circuit that 'feels' different than the other wire, more 'rubbery' and not as stiff. It's actually a little thinner wire inside than the rest of the circuit made to burn cleanly through (acting as a type of fuse) rather than over heating the circuit itself The problem has to be in this circuit, and something that 'opens' when heated. Good luck!

When you first start your engine the oil is cold and somewhat thicker, therefore oil pressure is a bit higher. If your bearings are worn, as the oil gets warmer and thins out, they will begin to knock. If you don't drive it and have caught the condition early, sometimes you can just replace the rod bearings, and it will be OK. However, after removing the oil pan and inspecting the damage, if you find that the main bearings are also worn, the engine will need to be removed and all bearings must be changed.(use "plastigage" to determine bearing wear) I strongly recommend that you change the oil pump as well, to ensure that new parts get a good oil supply. NOTE: some people attempt to just replace the oil pump when this condition exists...It is a total waste of time, and will not work. I know that this is not what you wanted to hear, but its a fact!
