How do I remove the power steering pump to replace the heater fan

You would need to remove the instrument cluster to get to the back side where the bulbs are.

First you will need a pulley remover/installer. Remove the power steering belt, remove bolts holding the pump, remove p/s lines, replace in reverse order,and fill pump. Start car and move steering wheel back and forth slightly, then turn the wheel all the way stop to stop Always watch that there is plenty of fluid in the reservoir. Check with dip stick, should be full to bottom mark;

The heater core is located on the inside under the dash.

Change the Fuel Filter first, than check the Fuel Pump.

Behind the headlight, you should see the nylon bulb holder. Turn it counter clockwise, about a 1/4 turn, and it should come out. Pull the old bulb straight out, and replace it with the new one. Don't touch the glass part of the new bulb with bare fingers, or you'll be replacing it again. Use cotton gloves or a paper towel. Put the holder back in the headlight, turn it clockwise until it locks.
