The interior light bulb in my suzuki swift 2006 keeps blowing. I have had to change the bulb twice in a month

There is short circuit in the wiring of fuse that keeps on blowing.

They are all separate circuits, start by checking fuses. Let's start with the interior lights check the bulb if OK check for voltage at the bulb use a test light if the light lights check the door switches.back up lights check fuse then check the bulbs and sockets, same with the fog lights check fuse (does the blue light come on?) remove the bulb and socket from one side, is the socket burned? replace as needed. I hope this helps, take care.

Yes

usually just pull back trunk mat from back side of trunk where the latch is you should see plastic clips they turn to the left to remove install new bulb and push back in clockwise to lock

Hopefully you have only blown the fuse for the interior light. To locate the fuse which should be in the main fuse box, the position and function of the fuses is normally marked on the inside of the fuse box cover and also in the owner's handbook. If you don't come right with these, work your way through the fuses looking for a blown one. To ease your search the interior light, which may be shared with some other circuits, the fuse it should be around 15 to 20 amps.

you need to open the bonnet and need to remove the bulbs in the head lights
replace with the new ones the bottom ones are the parking lights so change it correctly dont change the main lights

By putting cables the wrong way roundmyou most probably damaged the Alternator.
Check your central locking relay,must be fried.

you can first remove the glass of the tail lights. the glass can be removed using a screw driver. then remove the bulb. after that you can fix a new bulb.

either pin swiching which controls interior light un plug them and see if that solves the problem failing that master door slave inside driverdoor

Try changing the fuel filter.
