Blinker switch would suggest ignition switch- turn key to on but dont start car and jiggle key with blower turned to 5. Working only on 5 suggest resistors are bad. The resistors are inside the blower case with the actual blower or very close to the blower case outside and you can tell if they are bad(burned, etc). . If 5 is high then 1-4 goes thru resistors but 5 is direct with only a relay. There should be a relay (think it is under the hood in the electrical box) marked high blower or something similar. Pull it out and check condition of prongs and plug it back in and see if it works on 5. There is also the possibility of the speed switch 1-5 being bad or just corroded. Pull the switch and unplug the plug and check it for corrosion. Of course there is another way to see if blower is getting power by checking voltage with ignition switch on and fan switch on 5 but that means you have to remove the trim under the glove box and measuring with a meter. Hope these ideas help.
defference between a blower and a turbo charger when installed in a petrol engine

check the blower motor resistor
The blower motor on a Mercedes Benz 300e is changed by disconnecting the wiring harness and unbolting the blower from its housing. The motor is then lifted away and a new blower motor connected.
have you checked the fuse if so then you will need to replace the resistor for the blower hig and low dettings have you checked the fuse do you have 12 volts to blower if so then you will need to replace the resistor for the blower replace the blower motor
If there is one installed it should be behind the glove box. It is sitting on top of the blower inside the blower box
if it's a e-250 take the battery out and remove the three screws holding the blower,remove the wire harness,remove drain discharge tube,lift blower out of cavity and re-install with new blower motor.re-connect wiring harness and drain,tighten screws making sure the blower is installed in the correct position.install battery with tie-down holder for battery tray. check blower,by turning the blower switch to low then medium,and hi.listenn for noise or cage hitting frame. If ok..your done.
Blower motor: remove the glove box and you will see the blower motor and blower resistor.
Blown fuse. Burned out blower speed resistor. Faulty blower switch. Bad blower motor.
The blower is controlled by the blower switch, blower resistor, and relevant power relay.
usually the blower motor resistor pkg. located on or near the blower motor
do you mean a turbo? if i were you i woulg have it professionally installed
