The heater core is located on the passenger side, inside the car, under the dash, mounted next to the firewall. Look under the hood and you will see the inlet & outlet heater hoses entering the firewall. On the other side of the firewall is the heater core.
The blower motor should be under the hood. It is on the passenger side and bolts into the back of the heater housing.
Remove the glove box and you'll have access to the heater core, still not easy.
Check fuse if the blower is not working. If it is then replace your heater core. if its not then replace your fan switch.
The heater fan I believe is located behind the glovebox by the firewall. Just remove the duct and unbolt the fan.
pay someone to do it for u, what a pain in the ARSE
