heater blower?
I have a 94 Bonneville and I'm have issues with the heater fan. It operates fine as long as I don't turn the speed **** to high. Now looking at the wiring scematic it shows there is a high speed fan relay. I'm thinking this may be the prob but can't locate it. Anyone know specifically where this is at? Pics would help alot. TIA

It should be located in the underhood maxifuse relay center. This is under a plastic panel on the firewall. Blower motor is directly below. Since these relays could have been out at one time or another..the best suggestion would be for you to use your diagram wire colors to locate the correct relay.

The relay in the relay center checks out fine. I believe that is the blower relay but there is also a high speed relay that I am unable to locate. Am I mistaken about 2 relays?

We need someone with the manual for your year. I only remember with the **** climate controls there was one relay for the high speed, because it was direct to the battery.
When you say it checks out. How did you test it?
