When fan running, sounds like the fan is out of balance

if you are buying a new motor, instructions should come with it. but if not if you get the same type of motor with no instructions when removing the old 1 draw a little diagram.if you are not happy with anyof this you can always cut the electric cable as it enters the aerial motor and tape it off. do this when its in the up position.if you are happy with this please rate me. joe
SOURCE: what is the 94 Chevy Caprice Classic wiper arm
heres a wiper linkage asm diagram, the wiper washers are on the hood or on the cover to deck,then the hose runs through the wiper arm to a nozzle, if you remove the arms you can lift cover enough to look at the hose to washer connection,also check hose to arm they often break there good luck.

Your cooling fan relays are controlled by the Engine Control Module (ECM). What you are unplugging is probably the Engine Coolant Temperature Sensor (ECT). The ECM will default to "fans on" if it loses the circuit to the ECT. (It loses it when you unplug it) This is why the fans come on when you unplug the connector. The engine might be overheating because the ECT may be malfunctioning and "lying" to the computer about what the actual engine temperature is. If this is the case, the ECM is not turning the fans on because it doesn't "think" it is hot enough to need them. Then again, you could have a faulty temperature gauge that is making you think the engine is overheating when it is not. (If it is boiling over, then it is OBVIOUSLY overheating and you can just disregard that last statement.)
Anyway, the only way to properly diagnose the cooling system on your vehicle is to access the live engine data and look to see what temperature the ECM is seing while you take an actual reading with an infrared thermometer or a pyrometer and compare the two. Yhe thermometer or prometer reading should be within about 5 degrees of what the ECM "thinks" the temperature is. If there is a larger error than this then the coolant temp sensor should be replaced. If the reading is within this range and the temperatur gauge reads hot when it is not, then the gauge should be replaced.
Since the fans come on when you unplug the sensor, you know that all the fan circuits are working and the ECM is capable of controlling them, so it almost has to be a computer INPUT problem, not an OUTPUT problem.
