Yes the relay should be working on high speed...
It almost sounds like The blower motor speed control module is dead....
Thoughts guys?

I posted earlier the checklist of things that might help isolate where the problem is. If the control head isn't showing lghts and acting right, power may not be going to the blower control module, e.g.
But for the blower control module the red wire is hot all the timewith power from the battery; the purple wire takes the power from the module to the blower motor. That should have power under key on and request from programmer/control head.

According to the screen on my dash everything is working fine,you can adjust the temp,fan speed,A/C,defrost but nothing happens.
I looked in the maxifuse relay center and there are about 4 empty slots,but the prob couldnt be from one missing because it did work when i got the car and no one has been in there but me.
I guess i'll try swithing a few relays around and see what happens.

Hang back on the relays. imidazol mentions the procedure for checking the blower control module that is located on top of the blower box on the firewall. Tthat would be your next step, it appears relays do not control all the blower speeds and therefore can't be the entire issue.

What does the module look like?
I didnt see it above the blower motor so i followed the purple wire and that goes into the Maxifuse relay box.
Should i just buy a Blower control module and try that?How much are they?
Or should i try checking the fuses in the maxifuse center?
Thanks again guys,you have been very helpful.

Im Gonna have my mechanic pull the whole Maxifuse-relay board,i tried following the purple wire from the blower motor but that goes right back into the maxifuse -relay board,and i cant find anything that might be the module.
Im still stuck guys,i realize you guys might be frusterated by my lack of knowledge on the subject but i hope you realize my knack of knowledge about the Bonnie'*.
Thanks again
