Interior and exterior fuse keeps blowing on my 1999 sunfire

You had vehicle with no problems until you
paid a butcher to install the radio,so you know
how the problems got there

Now you go back to the radio folks or get it out of the
system & return the vehicle to as built working condition
yourself

it looks like an interior light or if fitted an undef bonnet light check to see what lights are not working and check for earth if not reply an i can investigate if you have more info,just a thought its not a LPG conversion is it ?

Something in that system is giving FEEDBACK into the system and burning up the Fuses, disconnect each system Individually and plug each one in one at a time and if the fuse does not burn out, then unplug it and do the next. When the one Burns out, then you have the Exact cause and then troubleshoot.

My Experience is the RADIO is the culprit

sounds like your light switch is bad..that's the only place all those share in common.

Voltage drop testing the starter circuit . Bad connection , battery cables etc.....
Starter Voltage Drop

You may want to check the water pump if it's overheating, have the motor mounts checked if the vehicle is shaking and the alignment and tire pressure are fine, first check the fuses for the interior lights. As for the clicking sound in front tires - please provide further explanation as to the sound, speed of vehicle when it happens, and mileage on the vehicle - could be the CV's but not enough information to assess.

The evaporator drain is plugged with debris and filling up the heater case. Remove the 90 degree elbow and clear the drain hole at the case.(pencil or piece of wire) You will know that's it when it dumps out a half gallon on the floor. Be sure to reinstall the elbow to keep out rain/ road spray.

sounds like theres a wire rubing against the exhaust and is now shortin out the fuse

Be sure you swapped like for like in the fuse ratings.
If one fuse keeps blowing then it will be a fault on the brake lights ,

Not sure but I advised you before!!
Any way last time!
You have to t/s the moment the fuse blows and elimate the systems (short) connected to that fuse, for sample, dis connect the interior light, install fuse, if it blows than it is NOT the interior light, keep going till you find the short!
