2007 cargo .
I know one fan is suppose to come on when a/c is on.Lately has not been happening.A/c blows warm till temp rises to about 198 then fans come on.
I guess this is the temp overide.After that a/c is cold .
does anyone know where the switch that turns on fan with a/c is.
Is it a inline pressure switch in a/c ?
Had a/c checked thats full.

you will find a relay or two next to the condensor fans near the bottom/passenger side of the fan grill. Check for voltage to the fan first...not sure which one is the primary and which is the secondary that comes on when the engine is hotter.
