HVAC blower

75

Asked by Apr 18, 2014 at 02:37 PM about the 2004 Cadillac Seville SLS FWD

Question type: Maintenance & Repair

Blower only works occasionally. I have installed new resistor. Fuse is good. In either heat or A/C, blower only works occasionally. Everything else works, and speed indicator displays normally. According to all fuse/relay locations, there is no relay. Why would it work intermittently? Any help is profoundly appreciated!

I removed ground block on passenger side behind lower door close trim/kick trim. Cleaned screw and metal plate of ground block, and made sure all ground wires were fully in the block and cleaned receiver threads to make sure there was a good ground connection. Has worked fine ever since.
