560SEL Blower problem

[benzoic]

The blower in my 88 560 SEL will not work. I have checked the climate control push button panel, the blower motor and the under dash resistor (looks like a honeycomb). The blower still will not work. The fuse is also fine. Is there an under the hood resistor or something else I am missing. When I push the button to activate the blower I do hear a "click" behind the push button panel but do not know what it is. Winter is coming and I need to have a functional blower. Please help if possible.
