What no. of fuse is 4 the radio

sounds like might b a main fuse. do u have a kick panel and a box under the hood? sometimes a main relay or fuse will cause many electric things to go out.

have you checked the audio fuse in fuse box?

Your mechanic is right..the circuit for the clock runs through the radio, and if the radio dies ..so does the clock

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

I dont think they are connected????? have you checked the fuse for the RADIO? you dont mention which engine you have, if the radio has an amp ck that fuse also (RADIO AMP). As for the locks ck the IP/IGN fuse and the B/U LAMP fuse. All fuses should be in the Instrument Panel Fuse Box.

I dont think there is a separate fuse other than in the fuse panel. some radio's may have one in back of the radio but I'm not sure about yours.

The headlight switch is common to all your problems except the quick flash of the turn lights on one side the quick flash is usally a bad bulb as the tailights have two and one could be out and it'll still work just it changes the flash quicker with no load too little and it'll not blink just stay on. Theres fuses for the dash lights but the tailight fuse has to be good for it to get power. Any crash damaged lights need to be checked out as water getting into the sockets can mke a problem. The marker lights on the front do'nt work either. Fuse or headlight switch now remember that the radio has a light in it too and if someones changed the radio alot of aftermarkey readios don't use the run light as they are on withthe radio on and this wire may be touchin ground or be hooked up wrong at the lights the wire color is brown. It's highly unlikly that alot of bulbs failed at one but the car is old. Start with fuses and if the tail fuse is blown and it has an odd radio pull it disconnect it and try another fuse

check for a good ground connection

The fuse for the cigarette lighter is the 15 Amp CIG fuse.

I would operate one by one mirrors left-right,radio, electric locks.
I would first dont operate side mirrors and observe if fuse remain then leave radio disconected (dont power on or remove its wire harness). If with radio disconnected fuse is not blown, i would use electrical locking and test again.
Good Luck
