1997 Bonneville SSe with auto air can not get anything dealing with heat or air to come on. The control console says it is doing its thing. No blower no compressor. checked all the fuses they are ok can hot wire blower it will run. I have searched the forum and can't really get any hits. Any ideas would be appreciated. Is there a way to test that high dollar blower speed controller.

Update replaced blower speed control module problem seems to be fixed.

Tell me more of this blower speed control module. I have a 98 that just sdid the same thing, we checked the blower its ok, compressor comes on but blower wont run. Blower speed control module?
