Ok, you need to check firstly that the motor is ok - probably is fine. Make up two long ish wires with female insulated spade terminals on. The wire needs to be able to carry 20A, so at least 2mm core. Remove plastic connector and replace with the spade terminals. Connect two wire ends to 12v source (cigarette socket or 12v battery) either way round. If you get spark and then the blower starts, its fine.
If not, dead motor. The motor assy is held in with 4 screws, upwards. Its very easy to see and remove if you lie on the passenger footwell facing upwards with a torch. NO PANELS NEED REMOVING!

If motor ok, then unlikely to be feed or switch. Remove the glove box (two screws at the bottom, visible just by looking at bottom with door open.) then remove the plastic panel. Its held by one plastic clip down the side, four screws visible, and pain in the backside, one or two screws behind the centre dash plastic. You will need to remove the radio, then the two screws upwards in the black plastic centre pannel (above the radio fascia) and one at the bottom between ashtray and socket. Then the panel will pull firmly forward (four plastic hidden spring clips)
Now you can see the screw holding the panel.
Remove the panel, and you will see a five way multiconnector dissapearing into the blower/heater housing. This is the resistor panel. Its held in with two screws. Remove it. If you are brave you can open it up, but you can make things worse - though if your only other option is a new one, cant hurt!
These are sometimes resolderable, with good soldering kit, but not always.
I can repair these if me

The blower is located under the glovebox,turn car and blower on,
and hit under the dash several times, if blower works , then it needs to be replaced, its just three or four screws that can be seen under the dash, good luck.

Holden Vectra - air con fan only works on maximum setting. If I switch to 1,2 or 3 nothing happens. I have checked the fuses, but all look ok?

It's common for interior blower speeds to only work on high when the blower resistor goes out. Usually located close to the blower motor. An electrical box/module with wires going to the fan motor. Goggle how to change it, and you'll know whether you can.

Where is the main air conditioning fuse located in a 1987 mercury sable

The fuse for the blower motor should be a 30amp marked number nine in the box near the steering column.
The fan switch and resistor provide the ground circuit.

My heat stopped blowing in my 1998 escort zx2 it just quit where do I start I checked all the fuses they are good is there a blower motor relay ??

"I checked all the fuses.." There is only one fuse, the 20A WIPER one in the instrument panel fuse panel which energizes the blower motor relay. The panel also contains the BLOWER circuit breaker which supplies power to the relay. If these parts check OK, there will be 12 volts on terminal 87 of the relay with the engine running and 12 volts on the BLU wire connected to the blower motor. If you set the function selector switch to any position other than OFF, the blower motor should operate at a speed you select by rotating the blower switch. If this doesn't happen, rotate the blower switch to HIGH. If still nothing, the thermal limiter in the blower motor resistor may be open. If still nothing, the function selector switch, the blower switch, the resistor or even the blower motor itself could be defective

Speed fun control airconditioned doesn´t work property.

Two possible areas I would check using an ohm meter. First is the blower resistor which is usually located by the blower motor and looks like a cement rectangle or a ceramic tube with wires attached to it. The resistor should have very low resistance but should not read open from the common lead to the other terminals. If it tests good test the continuity of the fan switch. Some cars have a fuse for the high and low blower speeds so you can check your fuse diagram and look for two blower or fan fuses. Good Luck.

Blower motor will not work

Do further tests at the relay to ascertain whether the fault lies before or after the relay.
Check power availability at the supply side of the relay contacts - should have 12v from a supply fuse on one side of the normally open contact (note -this supply may only be available when Ign or Acc sw is on).
If power supply is ok at the relay contact, check control input to relay operate coil.

If a ground (or 12v) operates the relay, operate the relay with a local ground (or 12v) and check blower motor runs.

If all above OK, check control signal from fan switch is arriving at the relay control coil.- if not trace wiring back to the switch.

My blower motor will not come on

run a 12 volt jumper to the blower motor connector and see if it runs, if it does remove the blower switch from the dash and check for a burned looking connector to the switch, if it is burned then replace the blower motor switch and connector, the connector and switch are avil from dealer.
