Why does my 2004 Chevy Colorado blower motor only works on high speed only?

My 04 does the same thing, never used to, it's an intermittent problem for me. Start with the resistor panel replacement (located by passenger firewall), if that doesn't work, its' probably the blower motor itself.

The problem sounds more like the blower motor resistor connector and/or blower motor resistor. I replaced the cable that had burn marks on two terminals, making a poor connection. The problem has not returned since last July.

It's easier to replace with the glovebox out of the way. gmpartsdirect has the harness and resistor as a package deal.
Their part number is PK15218254.

2005 Colorado 4 x 4 , my fan would only work on high (4) as well, for a while 1-2&3 worked intermittently the stopped. I found on my truck that the wire harness for the blower is in a spot where passengers hit it with their feet. I could wiggle this connection an it would work on all settings again, I fixed it by making the connection better and electrical tape- I hope your fix is as simple.

Swap the relay with a known good one, many of the relays are of the same part number. Keep in mind that the blower motor relay only controls the high speed function. The blower motor speed resistor and the blower motor switch controls the lower speeds.

Should be behind the glove box. The blower motor speed resistor is located under the hood, on the firewall, passenger side, close to the blower motor.
