My air conditioner was working fine. Not cooling really cold. I turned off the air conditioner and when I tried to turn it on again it would not blow. The air conditioner and heater both are not working now. The compressor is still kicking in but the blower is not working. Where do I locate the relays for the blower motor.

IF YOU HAVE AUTO TEMP CONTROL, TRY THE SELF DIAGNOSTIC, TURN KEY TO "ON", PRESS heat/FLR BUTTON, Slide blower speed
control lever to HIGH position. Press and hold both COOL and WARM TOGETHER FOR 3 SECONDS Display will show "--" for
about 20 seconds, then will display any codes in memory, If 75F or 24C appears, voltage to the EATC assembly has
been interupted, try the test again! Post codes that appear. If the blower does not work, check or replace the Blower speed controller, to find it look behind the right side of the dash, if you don't have auto temp, find the blower resistor in the same spot.

Hey Merlin, I have the same issue and I am almost positive I have a blower resistor issue but I have auto temp control on my 1993 cougar. I did the diagnostic and got a 88 degrees. The fan will blow, but only on high setting, no variable speed. Ford wants 250$ for the resistor. Sound to you like that's the issue?

Thanks for the reply. Unfortunately because it is the auto temp control ac unit it is not the standard blower resistor on most websites. I too initially thought that but I actually purchased the resistor on the link and it is not the right part. I was just hoping doing the diagnostic that the previous guy talk about might solidify the issue so I dont spend 250$ if I don't need to. As far as I can tell it is a specialty part from Ford. Like I said before the fan works but only in high I can manually put it to high output or if the auto temp computer commands full fan speed it will turn on high, but there is no in between settings on the fan speed. Other than that the system works fine.
