Hello everybody !
the HVAC climate control panel of my Cougar does not works (is the LCD european style, see picture below).
The last weeks, the HVAC control panel worked perfectly in the mornings (cold exterior temperature), but in the afternoons after several hours under the sun, the HVAC control panel does not worked.
Finally this week, the HVAC control panel does not works anymore.
When I turn the knobs and press the buttons, it does nothing:
I have checked (including a wiggle test) all the fuses of the two fusebox (specially the fuses number 23, 34 and 37 related to heater blower and AC system) and is all Ok.
I have checked also the blue color relay R3 (related to AC) and replaced it with a new one. The relay works ok (activates when I turn on ignition switch)
I have do a wiggle test of the rear connectors and cables of the HVAC control panel, but still not works.
Please, has anyone had the same problem?
Any help will be appreciated.
Thanks in advance and sorry for my bad English.
My car is a 1998 Ford Cougar 2.5 manual transmission.
This is my HVAC control panel:
SOLVED !!!
I found the problem doing a wiggle test to the cables under the dashboard.
The problem was a cable connector in the Fuse box under the steering wheel.
The connector have the reference C371 in the Ford TIS wiring diagram.
In the following pictures you can see a pin open and the connector melted.
This have cuased poor electrical contact and finally the pin open and no power to the HVAC Climate control panel.
As I have read in other forums, this is common fault in the Cougar and the Contour (Mondeo), and most cars have this connector melted.
You can read about this same problem in this Contour forum:

Luckly this connector is still available new.
I bought a new connector, replaced and the Climate control works again.
I also have added grease for electrical contacts to the pins (Liqui Moly 3140).
Battery Clamp Grease

When I turn the knobs and press the buttons, it does nothing:
- the LCD screen show nothing.
- the illumination of the LCD screen is always off (even if I turn on the headlights).
- the blower does nothing.
- the AC clutch compressor not activates.
