    2003 Bonneville blower doesn't always work after starting car. It may come on after a few minutes. Is it loose connection someplace?

  • Anonymous Oct 10, 2008

    I posted earlier in the wrong spot.

    Where is the switch besides what is in front of me when sitting in the car?

    Blower may start when hitting a bump in the road. So it has to be a loose connection someplace. But where?

    Mine was doing the same thing, I took a water bottle banged it a couple of times then it would work well this only worked a few days and now it does nothing. There is heat but no blower, so what is the real problem?

    Have the same problem. Bumping it for a year, it has breathed it's last breath. Repair shop said $800. I saw another owner had $350, can handle that.

    Has anyone purchased the blower and installed on their own? How difficult is it.

I had the same problem on my 2002 Bonneville and I was able to tap on it and make it work for nearly 2 years, but I finally had to replace it. It cost me $350 dollars for the new blower motor and labor.

I also bumped mine for a while before I removed it and blew out all the dust (grafhite) from the brushes wearing out. That lasted a few months so I did it again . Then I ordered one online and installed it . It lasted about one year. I removed it to clean it and found the brushes very worn to the point of not making contact with the armature . Once I get the proper tools together , I can remove it in less than 15 min. but you need to be almost upside down when you remove the three bolts and disconnect the two or three plugs and the 4 inch long tubing.Simple and easy for me but I have been in construction for 40 years and this is similar. You can probably do it or supervise some else who is ok working from that position. I have not found anyone selling just the motor so you will probably replace the motor and fan blade attached to it. Cost about 50-100 dollars. I believe these companies intentionally use crappy material in their brushes so they will wear out, but how do you find out who uses good parts? good luck . hope I helped you in some way.

The blower motor is bad,I have the same problem and I also have been tapping it for 2 yrs.The only fix to this problem is to replace the blower it isn't cheap but it is the only solution

Posted on Dec 08, 2008

If I hit a bump in the road, the blower will start sometimes. If I it is working and I turn it off then back on it more than likely won't work.

Pardon my ignorance, but where would the switch be located?

It seems the problem would be closer to the blower itself.

Blower stopped working on my 2003 bonneville could it be a fuse and if so where is the fuse box

It could be a fuse. Fuses under the back seat.
Chances are that it's the blower itself. Pretty typical for our generation of Bonneville. I have a 2005 GXP and replaced the blower at about 75,000 miles. I can't remember the car before that I had to replace a blower... maybe 20 years ago?

Anyway, the blower is under the passenger dash.
Remove the panel under the passenger side dash; I recall two small screws.
There may be a couple wires to unplug from this panel.
The blower motor is located right above the passenger toes.
Unplug the three wire plug.
Remove a small rubber hose. It has one right angle bend. It's about the size and length of a big thumb.
Remove 3 small screws on the fan, and the fan comes out.
