The fact that the light comes on is a good indication that the electronics are working, the most common problem is a vacumn leak. This can be a damaged or cracked vacumn line, a bad check valve, or the dump switch on the brake pedal

Could be either a bad pump drawing to many amps, or a bad relay, or any push connector which has corroded, even a ground wire.

Please refer to the owners manual.

What makes you thing it's a sensor ? A lot of thing's could cause this , taking the vehicle to a qualified repair shop is what should be done. They will do a full system scan . ENGINE HOT A/C OFF Cooling System Description and Operation Coolant Warning Messages The radio will display the following messages if the following conditions exist in the cooling system. • Engine hot--A/C OFF will be displayed if coolant temperature is above 117°C (243°F). For imports 115°C (239°F). • Engine coolant hot--Idle engine will be displayed if coolant temperature is above 118°C (245°F). • Engine overheated--Stop engine will be displayed if coolant temperature is above 123°C (253°F). Cooling Fan Control - Two Fan System The engine cooling fan system consists of 2 puller type electrical cooling fans and 3 fan relays. The relays are arranged in a series parallel (S/P) configuration that allows the engine control module (ECM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block. The ground path is provided at G104. During low speed operation, the ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the low speed fan relay coil, closes the relay contacts, and supplies battery positive voltage from the low fan fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan S/P relay and the right cooling fan. The result is a series circuit with both fans running at low speed. During high speed operation the ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. After a 3 second delay, the ECM supplies a ground path for the high speed fan relay and the cooling fan S/P relay through the high speed cooling fan relay control circuit. This energizes the cooling fan S/P relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time, the high speed fan relay coil is energized closing the relay contacts, and provides battery positive voltage from the high fan fuse on the cooling fan motor supply voltage circuit, to the right cooling fan. During high speed fan operation, both engine cooling fans have their own ground path. The result is a parallel circuit with both fans running at high speed. The ECM commands the low speed cooling fans ON under the following conditions: • Engine coolant temperature exceeds approximately 94.5°C (202°F). • A/C refrigerant pressure exceeds 1447 kPa (210 psi). • After the vehicle is shut OFF, if the engine coolant temperature at key-off is greater than 101°C (214°F), the low speed fans will run for a minimum of 60 seconds. After 60 seconds, if the coolant temperature drops below 101°C (214°F), the fans will shut OFF. The fans will automatically shut OFF after 3 minutes, regardless of coolant temperature. The ECM commands the high speed fans ON under the following conditions: • Engine coolant temperature exceeds approximately 104.25°C (220°F). • A/C refrigerant pressure exceeds approximately 1824 kPa (265 psi). • When certain DTCs set At idle and very low vehicle speeds the cooling fans are only allowed to increase in speed, if required. This ensures idle stability by preventing the fans from cycling between high and low speed. DTC P1258: Engine Coolant Overtemperature - Protection Mode Active

Things you should check is locate the fuse box and find the label: Generator/Alternator. It could only cause by the blown fuse. If the fuse is ok, then you maybe experiencing faulty alternator. Your battery will last for 10 to 25 minutes only and everything will shut down. I suggest get your alternator check by electrical mechanic.

Try a little spray silicone in track (felts on sides) where window slides to allow for easier movement. May need to clean window after but let silicone work in first. Put window all way down and spray as much of guides as you can.

Need to do a load test on battery sounds like a bad cell Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/craig_a14a43e01fd0835a

Yes , there is a relay . It is energized by the PCM - engine computer . When you push the A/C button on the climate control panel ,it sends a voltage input to the BCM or strait to the PCM .When the PCM see's this it will energize the relay ,if it see's the correct input from the high an low pressure switch .
