AC Will not engage
Needed to replace dual radiator fans , because the drivers side would not
work , as car started to get hotter the other fan kicked in, the one for a/c and
over heating . I also notice that a/c didn't work ,so I thought because of fan
that's why. I changed fan and all that is good , fan works when needed.. But
a/c never worked. Blower is ok goes from 1 to 4 . The lights turn on for a/c
even on high . But no engage . What should I check.first.
First make sure there is freon in the system. If no freon in system it will not come on.
If there was no freon the over heat fan would stay spinning ,with a mariner and a escape they stay on when the pressure senser is reading to low or to high in freon, I know that because I had that problem one ,and fixed it from learning here . So just don't know why the fan and a/c went out at same time now.
i lost my booklet for fuses and stuff, what controls just the compressor alone what no# is the fuses and relays to check . Doesn't ford have a download site for the booklet
