One is the mode switch and the other is the temp control switch. Do this, start the engine then open the hood and listen for a hiss indicating a vacuum leak on the vacuum reservoir or a broken hose going to the heater control the hoses on this vehicle have to be very brittle by now so get some vacuum hose and have at it I think the vacuum reservoir may be mounted to the hood. I hope this helps. Take care. If this isn't it you can use testimonial to contact me with questions.

There's no switch, I have a hunch the problem is in the fuel tank. If you fill the tank all the way to the top does it still do the same thing? Does the tank take as much fuel as it used to? There may be a crack in the neoprene hose that connects the fuel pump to the tank module. I hope this helps. Take care.

ENGINE HOT A/C OFF
Refer to Cooling System Description and Operation
Do the radiator cooling fans work ?
The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a Series/Parallel configuration that allows the engine control module (ECM) to operate both fans together at low or high speeds. The cooling fans receive positive voltage from the cooling fan relays which receive battery positive voltage from the underhood fuse block.
During low speed operation, the ECM supplies the ground path for the low speed fan relay, which is Fan 1 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 Fan 1 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 Series/Parallel relay, which is Fan 2 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. The ECM grounds the high speed fan relay, which is Fan 3 Relay and the Series/Parallel relay through the high speed cooling fan relay control circuit. This energizes the Series/Parallel 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, the relay contacts close to provide battery positive voltage from the Fan 2 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.
When the requests for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph. This is to prevent a fan from cycling ON and OFF excessively at idle

You need to do a hard reset of your clock. On the touchscreen, select "MENU", when the screen changes, touch the lower left corner and hold until the PIN screen appears. Now enter the PIN code 295660, touch "NEXT", "PAGE", then "SET TIME".

Really not enough information to troubleshoot. For example, when this happens is the car at constant speed without you changing the gas pedal position, and if so, how fast are you going? To hazard a guess at this point, could be your transmission is either slipping or the car is at a speed shift point (e.g. around 40 mph) and it thinks it should be briefly downshifting.
