Question about 1999 Mercury Cougar

A/c or heater not working

My a/c and my heater quit working. I have already bought a new blower, motor, new fuses, and a new relay. And I have checked for shortages. What could be the problem?

    Are you getting any air blowing from the blower motor? Have you tried checking the fan control knob/switch?

The heater fan motor quit on my 2002 Ford F-150 Super Cab and I can't find a fuse for it. How do I repair it?


Owners manual lists the fuses as :
Engine compartment fuse # 105, 40A
- This is the power to the blower motor relay to drive the blower.

Cab Fuse Panel, Fuse #22, 10A. This is the power to the switch in the HVAC panel.
- This fuse through the switch to operate the relay coil on the blower motor relay.

The other thing to check is the blower motor resistor, to see if there is any damage to it ( usually this is the blower only works on high )
This is behind the glove box

Heater blower motor just quit working during heavy rain.checked all fuses glove box and under hood;gm told me it was a relay behind the blower motor panel.ps 1992 Chrysler new yorker salon how do i replace...


The rain had nothing to do with it. What ever GM told you was a quess,unless they worked on it. You never change parts until you know their bad. Have to at least know how to test relay, if you do find it. Stop by dealer,they will come out and remove it for free

Check the fuse box in the car first then if that dont work check the fuse block under the hood also check for a bad relay. And if that dont fix it you may need a blower motor
