Best to you.

Changing a serpentine belt shouldn't affect any of the electrics. Changing a starter only carries a risk when disconnecting and reconnecting the battery before and after swapping the starter motor. Done correctly that risk is low.
So, No clock, no heater control panel, no rear view mirror compass and both power door locks don't work? Does the car still start and run normally? Do the power windows (if fitted) still work?
This still sounds like a fuse issue. How did you test the fuses? Fuses can look OK but still be 'popped'.Somewhere around 2001 some changes were made to the fuse box layout on that model. Is your dashboard fuse panel the smaller square 18 fuse panel or the larger, longer 32 fuse panel?

It is located in the SJB smart junction box , it's a fuse / relay center / microprocessor ! Fuse # F2.10 30 amp . location -behind left side dash panel . Also check the accessory relay . Top relay left side , same location SJB .

very old post, but I do this , to show others how to find facts on cars , im using Alldata dot com. its all there, all the time.

in the fuse box. in USA? Canada?
the fuse data is in the glove box, op guide, lost that.?
if yes, google that, they are free and everywhere.
, but usually the box is, near left toe in LHD cars.
i logged in to alldata dot com. for you.
there are 3 heaters, 2 in mirrors and the rear window
one controller for all, and 2 fuses.
fuse F18 and Ef21
now you will ask where they are, ?
E means engine compartment fuse box. (hot with lights on)
F18 states I/P fuse box. instrument panel.

ok , i click on the fuse box , page Engine bay BOX
Ef21, is dead center in the box. 4th fuse down
marked, ILL RH
F18 this is the CAB box. in the passenger compartment.
left toe loc, most suzuki cars made in N/American.
the fuse is on left side, bottom marked, heating mirror.

Now you know, for 1 car, 1 year, and one country.

Hi,
You remove the door panel on the inside and it is bolted on from the inside. One wire clip and 3 bolts. Takes longer to remove and replace the door panel than replace the mirror....look for a hidden screw under the armrest , under the window/door lock button panel and sometimes behind the reflector or light on the bottom of door..Usually there are 3-4 screws and then the rest of the panel is held on by plastic clips. Get the screws out, then work a flat screwdriver or putty knife around the sides and bottom of panel, then lift upwards to get the top sealing side out of the track where the window runs.....Mike

First thing to do is test these fuses with a tester light. Check the A/C cruise control fuse 10 amp (left side of dash in panel), heated mirror fuse 10 amp (right side of dash in panel), this is also where you will find the circuit breaker and relay for the rear defroster. Test the breaker for power in and out. Feel the relay to see if it clicks when you turn on the rear defrost

I researched the maintenance manual. The fuse you need to replace is fuse 20 in the under dash fuse box. It controls side windows, washer motor, rear view dim function, and possible seat memory. There are a couple that link to the mirrors, but this is the one for this problem.

You need to remove the plastic plate that cover the mirror joint from the inside and undo the three bolts.

There are two tiny motors in each mirror. one for up/down. One for side to side. They have jack screws (plastic) that fit into the motors.

You can manually put your hands on either side of the mirror and force adjust it. If you hear a ratcheting sound, the jack screws are OK. Then repeat with hands on top and bottom.

If you hear ratcheting and mirror stays where you stop it, that means one of the motors is bad. The motor assembly is available as a separate part.
