Question about Chevrolet Malibu
97 Malibu 3.1 L v-6 cooling fans wont turn on..(ORIGINAL PROBLEM)After following suggestions here, still no luck in finding WHY. put in switch at fan2 electrical connection, direct power from battery. This WORKS to turn fan on/off GREAT...but keeps setting P1652 (& P1653 one time) Erase code, MIL goes away, atart car, no MIL, but within 2 mins. comes back on. Something WACKY w/Relay center under hood too...while testing the 3 fan Relays,all tested good, but the MODE relay, 5 pin, where plugs in, seems to have reversed polarity? More positive then suppose to have? What could cause this to happen? AM I fighting a losing battle? Dont want overheating, but cant drive around in limp mode either! Worst gas mileage EVER!

SOURCE: Cooling fan wont work
The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

SOURCE: cooling fan relay 1998 neon
on the left(driver's) side of the lower rad support. It's a small flat relay with a plug on the bottom and usually has a blue colored front. held on by two screws. Also, there may be more rad fan relays in the underhood fuse/relay box.

are you getting codes for incorrect gear ratio and shift solenoids? if so then you are in need of a complete transmission overhaul.
However before you do that, check on the drivers side of the engine compartment under the battery tray is a wiring harness that runs next to the transmission, after a leaky battery and years of service, the pink wire that goes from the tranny control module, on the passengers fender, to the tranny gets corroded and brakes inside the insulation, check powers and grounds and if all is ok then bring it to a tranny shop, the sun gear brakes alot in those units, had the same problem on my cousins 3.3L and had to do an overhaul.
sorry to be the bearer of bad news.

Here's a maybe answer. You keep changing the starters and testing things and it's not working, here's something you might want to consider.
It might be the ignition switch itself. IE where you put the key in, you said you turn the key and nothing happens. I would suggest that it might be the ignition switch. But since i don't like ford to much i wouls suggest this as a maybe only, not to familiar with ford. Hope this helps.
