2005 Bonneville SE blower moter/fan doesn't come on

[homeboy517]

All the buttons on the climate control panel light up when pressed but the FAN / BLOWER MOTOR doesn't come on. It doesn't matter if I try using the AC or HEAT. Please share you thoughts on how to troubleshoot this, as I'm not sure where to start.

This is becoming a common problem as these cars age. The brushes wear out in the blower motor and it requires replacement. You can remove the lower hush panel that is below the glove box. There are two 7mm bolts and a push pin style fastener which hold it up. This will reveal the bottom of the blower motor. You can try tapping on it to see if it comes back to life to get a little bit of use out of it still, but ultimately, it needs to be replaced. It is held in by three 10mm bolts (I believe) and the electrical connector. Not a bad job at all. Replacement motors aren't too pricey on Amazon or Rockauto.

i bought one off of ebay and it made it almost a week and burnt up

mine was suuuper loud, cleaned all the crud from the inside of the motor and all quite again. so it might need just a cleaning

I changed mine on my 02 se...I thought it was kind of a beooootch cause of laying on your back...pull the carpet back some it gives you more room to remove and install the unit

just looked on rockauto totally different design might be quick and easy

I think 2003 and up got a newer and more compact blower motor, which makes replacement much easier. Might still have to get on your back however.

i will definitely say flexibility is definitely helpful in the replacement on these even the 03+

Yup. If you're a larger person, I'd suggest removing the passenger seat to make this even easier. Luckily, I'm small and relatively flexible. I was laying on my seat upside down. Haha!

you can also adjust the seat if they are the full electric do its easier to lay on
