not kowing the year of your car its not easy. if its a older car then check the carb has not got blocked jets if its the later car change the fuel filter first then change the crankshaft sensor

Depends if heater switch is electrical or manual. If manual , could be cable is bent, if electrical , new switch needed.

hope you dont have to take the roof liner out to fix wiring

all that comes up in searches
is fiat punto fixes for that area of wiring

This may be a puzzle...
The seicento (I drive the same car) likes to create problems in the heater section of the cooling system. The small pipes to it (behind the carburator) may be blocked or the entire heater may simply be dirty. Flushing the system with a water hose may help. Usually this problem starts slowly and goes away if you re-start the engine and then excellerate a few times. Check if your heater blows hot air - if yes, and if he keeps blowing hot air (does not cool down and get cold) ther is no blockage. If you have a blockage, your heater will only blow hot for a little while and then comes normal cool air - if this is the case, you have a blockage right in your heating system which runs your cooling system hot and the cap of your cooling tank will start leaking. This is a comon problem on older Seicentos....
Other general problems can also be the case, like defective thermostat, fan motor does not come on (check fuse and relais first).
In some cases, ther might be some air trapped in the cooling system and doing the above will also cure it. At last, check if your water pump is working.

you have tripped the inertia switch, (there to cut off the fuel pump in the event of a collision), you need to reset the switch by simply pressing it back in.

check your battery cables make sure there tight and secure but what i think you will find is a fuseable link going from the battery to the wiring harness has blown and once you replace that!! then you need to find the component that cause it to blow which wil probably be the heater motor also check and make sure your alternator belt didnt fall off

Sounds like you have a charging problem.Take it to a service place,have them check it for you.

check fuses first, if all fuses ok then u have bad cig lighter.
