Expert:  Roy Belding replied 4 months ago.

just so you know, the automatic system has no relays for the blower. are you sure it is automatic climate control??

Customer: replied 4 months ago.
I don't no much about Buicks, But it has push buttons and no knobs to turn.
Expert:  Roy Belding replied 4 months ago.

ok, first, I see you posted the question again. do you want to stay with me or work with another tech??

also, the 2 relays you listed are for compressor control, nothing to do with blower operation.
