Why the first two speeds of the heat blower do not not work?

Probably the blowere relay, may be the switch or the blower motor however. This is a bad resistor, very common problem on Malibus. It's located under the dashboard, behind the glove box. Here's a site from another forum with the specific directions: I had the same problem with mine. I went to a junkyard, and bought a used part to fix it. The part behind the dash that you use to change the speeds of the blower is what needs changed. It is actually very easy, and about $30. It is worth doing, I was done before I left the junkyard (I wanted to make sure theirs worked).

Normally when some speeds work and others don't, the problem is a bad, Blower Motor Resistor Pack. You will find it somewhere near the blower motor.

If the blower works on slower speeds only I would suspect the high speed blower motor relay (under the hood in the power distribution box) or the switch itself. The blower speed resistor is working if all the slower speeds work.

Why would our 97 lesabre blower work sometimes and sometimes not?

If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.

How do you find fault on heater fan not workin mk3 mondeo?

If all speeds do not work, suspect the fuse, the switch, the switch connector or the blower motor. If only high speed works, suspect the blower motor speed resistor. If low speeds work and not high, suspect the blower motor relay.

Just had the same problem. First my blower motor would onlywork on "high", and then it started to change speeds and shut off by itself. Replace the resistor mounted in front of the blower motor.It costs about 40.00 at a dealer.
