The thing that could cause a knocking noise in your car is the same thing that could cause it in all cars A rod that or a flat lifter. it all really depends on where the knock is if its higher and to the back of the motor, it could be a motor mount
It's an engine, not a motor, and a number of things. If it's a leak which allows coolant into the engine, it could get into the combustion chamber. This could eventually cause detonation, which could scar and damage the pistons. The vehicle could overheat, as well.
lack of oil
defective motor will not run, also cause the blower motor speed resistor to burn out and eventually blow the fuse. a motor with defective bearings will draw excessive current causing either the fuse to blow or cause the motor to overheat
Debris in the hoses or reservoir could cause the motor to overheat. Also, running the pump without fluid could do the same.
could be the resistor on blower motor is bad
Could be the starter relay
It could.It could.
Freeze plug at the rear of the motor. Between the transmission and the motor.
if the motor is turning then it could be off the track or a gear might be stripped.
If overload is not the cause, then high temperature could be caused by blocking the cooling of the motor.
There could be two separate problems. Check the blower motor resister, and the ABS sensors for problems that could cause this.
the motor could pre-detonate or "knock" that can cause damage
A busted motor mount, for one.
A loose engine mount would not normally cause the engine to fall out because each car has several motor mounts. A loose mount could cause the motor to be off of balance.
common cause is the wiper motor. Could hotwire it to see if it works or not. If not that then could be the multifunction switch.
can be the heater blower motor resistor located in either the ductwork or under hood near blower motor on firewall
Eventually the motor will burn out.
It could possible that you broke a motor mount. Depending on whether the vehicle takes any abuse or not. Or it may just be loose.
The motor would operate above its rated RPM. The motor would start to get hot as the current draw would be greater. This might eventually burn the insulation off of the windings and cause the motor to short circuit.
It COULD be the blower motor, or the evaporator could be plugged up with dust.
could cause internal damage to valves and or pistons !
Most likely cause is a failed blower resistor.
plates in the battery are arcing together. causing battery to short out and get hot. could explode. or you have a dead short in system. both will cause battery to get very hot.
