The Blower Motor is on the Passenger side, just under the dashboard. It's round, and has a two wire plug coming out of it. If you are having problems with the Blower, it could simply be a loose connection on the plug. Wiggle the wires with the Key ON, and the Fan switch turned On, and see if it starts working.
Loose connection or blower motor is bad
Start by checking the fuse. If the fuse is good, apply 12 volts directly to the blower motor. If the motor runs it is good. Check all the wiring for loose or burnt wires. If all this checks out, then the Blower Motor Resistor Pack may be defective, or the blower motor speed switch itself.Start by checking the fuse.

When blower comes on the windscreen wipers are faster then slow,and cd player turns on and off any explaination available could it possibly be that you have a short or wires loose and touching?
Connections get corroded and loose, causing resistance which causes the wires to heat up and melt.
It could be the blower motor, control switch, relay (if your vehicle uses one), loose connection or bad fuse.
connection could be loose. Or the switch might be going out
problem with electrical wires attached to the blower motor , they're to loose, try to paste them again
Could be a bad blower motor, or, look to the blower motor resistor mounted on the engine firewall on the passenger side near the top of the firewall inside the engine compartment. It will have five wires going to it. It is likely either burnt out, or the wires have shorted at or near the resistor.
Loose connection or blower motor? Bad blower motor? Loose fuse? Bad fan switch?
