A have the climate control but have a problem to take of the cover that covers the control and the radio. If any one can tell me how to remove it I will put in the new control and see if that will stope the fann.Thanks

Hi not sure if this helps , but with my lesabre there is a ground under the carburetor that knocked out my A/C, horn , wipers and dash lights. part cost 3.00 . I just lead soldered to the clip and bolted it down and everything is working fine.

check the fuse box and under hood ,check one by one with the climate control on and radio lights on , and you will see when the radio its off or on.

your blower control has gone bad it is under the cowl panel on firewall only way to repair is replace this it will be about in the middle of the air box. should be a plastic panel with i think three finger screws you remove it and will see it

it is probably a solenoid or vacuume motor that has failed where the heater core is located
