What is wrong with my cars heat and air? I have a 2001 Mercury Grand Marquis.?

Question

It heats up and cools, but even on high, it just barely blows like it is set on low. I think it might be the blower motor. But not sure. If so, what does it take to fix it? Will it be very expensive? My brother said the whole dash will have to come out to get to it. Is that true? I would appreciate anyones input or suggestions since winter is almost here, and I am freezing when I first start my car. Thanks.

Answer 1

The blower motor is under the hood area on the right side, it has 3 bolts holding it in, and wiring on top of it. you could have a blower speed controller stuck, or switch that is bad, but the first thing to do is take the blower motor out and check the cage on it, and then look inside to make sure thatt there isn't anything restricting air as it blows thru the evaporator core, I have seen mice make nests in blower motors and in the case area. It should only take 30 minutes to remove the blower motor, and doesn't really need special tools, a 8mm or 5/16 socket, ratchet and a couple of extensions.

Answer 2

Without seeing the car can only guess! But the fan switch is usually the 1st area to check. Is inexpensive and easy to change. And no the whole dash does not have to be removed. As the person earlier said, if it is the fam motor, it is under the hood and fairly simple to exchange. Also there are lots of aftermarket sources for both parts, all much cheaper than the dealer.

Answer 3

Probably the fan switch, possible blower motor Probably not the whole dash put part of it. Could cost alot at the dealer. Find a reputible small shop to fix it. around $200 or less if it's the switch.

Answer 4

If the blower motor sounds normal when you change speeds, it's the vent controls. Stuck door, bad control solenoid, vacuum leak. You should have a Chilton's or Clymers manual for the car. It will tell you what's involved in changing the motor.
