Hyundai Tucson shifting problem

The fuse is in the engine compartment fuse box and is marked 'A/Con'. It looks like a Relay to me and as it doesn't have an amperage, my guess is that it is a relay. The different sites have slightly different variations, but the thing to check first is the relay. You mention 'heater coil', that is on the engine coolant circuit and only provides hot air. The AC compressor system has an 'evaporator' up in the dash and only supplies chilled air. I trust the AC job was done professionally with a Gas Recovery machine to create a moisture free vacuum before adding refrigerant gas. It can't be done at home. I wrote a Fixya Tip on it.

it looks like you have a problem with the shifting cable. release the cable from the transmission side and check functionality. replace or adjust .

If your model has 4wd, the computer decides when it is needed.
There should be a button on the dash that will allow you to lock it into 4wd up to 30 mph.

make sure all doors are really closed and the door sensors are not falsely telling the alarm module that its open. if not then its the shock sensor in the alarm module acting up

i believe its a 2oA fuse.

Check the relay first then the fuse. If they are not bad then it might be that the switch is burned out after that it will be in the shift modulator for the 4 wheel drive. If it is the modulator then you will need a new one.

There may also be a Haynes Manual available, but I have not found one for your vehicle yet.

Hi there, the Common Rail Diesel Inyection (CRDI) 2000 cc 112 Hp M/T have a big trouble on cluth plate, and sounds very loud between 1500 and 2000 rpm on 2,3,4 shift.That motor has too much torque and cause excesive wear in the cluth roll and plate so starts roominess in the cluth system. You could change those parts but quickly the sounds come again. Hyundai is the resposable of that damage. I hope in the near future recall the CRDI model 112 Hp and replace the cluth.
