I have a 2000 Cadillac seville sts, my blower doesnt run! Changed motor and tested its fine,no blown fuses, changed the resistor,im lost and cold. Rear blower works. All my lights are on the climate control panel could that be bad?

Welcome to the forums Erd,
hmmm... I think there is an additional module for the climate control ..
I'll ask for one of our specialized GearHeads to please review this problem, hang in there...

Pretty sure Caddy would use an automatic HVAC system, so it should have a blower control module rather than a resistor block....

The obvious question is, do you have power AND ground at the blower motor?

If you don't do you have power and ground at the blower control module?

Do you have a variable voltage input into the module when you change fan speeds? That power is provided by the IPIM(instrument panel integration module).......

Only a high end scan tool, like a Tech II can get the data for this....
