Power door locks won't work and the instrument pnnel lights won't turn on. I replaced blown fuse a 20mp one in position 14 I believe. worked ok till I tried to lock the doors, the fuse blew

Have you had vehicle check for DTC'S diagnostic trouble codes . Check fuse's an relays , find wiring diagrams to see what controls these systems ?
Radio/Battery fuse , fuse G 10 amp located in the right instrument panel fuse box . Do you know where this ?
Fuse Block - Right IP - On the right side of the instrument panel
An there is one on the other end of the instrument panel ,driver side .
Fuse Block - Left IP- On the left side of the instrument panel The fuel an temp . gauges not working is probably the step motors inside instrument cluster . GM had problem with this 03 to 06 .

Daytime Running Lamps (DRL)
The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level. When the BCM receives this signal it will either turn on the daytime running lights (DRL) or the headlights. Any function or condition that turns on the headlights will cancel the daytime running lamps operation. With the headlight switch in the OFF position, the headlights will either be turned ON or OFF, after an approximate 30 second delay depending on whether daylight or low light conditions are sensed. The HTR A/C IGN fuse in the underhood junction block supplies ignition positive voltage to the daytime running lamp (DRL) relay coil circuit. The DRL relay switch contacts are connected to the low beam circuit. When the headlamp switch is placed in the OFF position, the BCM will either turn on or off the daytime running lamps, depending on whether daylight or low light conditions are sensed. The BCM energizes the DRL relay, closing the switch contacts and grounding the low beam circuit. Ground is provided at G101. The DRL illuminate the low beam headlights at a reduced intensity. The DRL will operate when the ignition switch is in the ON position, the gear selector is not in the PARK position and the parking brake is released. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate.
DRL operation in Manual Transmission equipped vehicles will occur when the ignition switch is in the ON position, and the parking brake is released. - check fuse's an relay first.
Door Lock System Components
The power door lock system consists of the following components:
?€¢
Driver door lock switch

?€¢
Front Passenger door lock switch

?€¢
Body Control Module (BCM)

?€¢
Relays: Driver Door Unlock--if equipped, Door Unlock, and Door Lock

?€¢
Door Lock fuse 15A

see the diagrams for power windows+doors and fix it. God bless you

Sounds like a major fuse blown.
Any wiring disconnected or stripped near the pump ?
Have you checked the major fuses around the battery and underhood fuse box ?

You blew more than 1 .

The HUGE MAXI FUSE is probably burned... IF I remember correctly, it is a 80 or 100 Amp

as the lights worked when you held the switch in position , check/ replace the light switch

1997 Honda accord nothing on instrument cluster works,only the battery light. Power windows will not work. shift lock solenoid doesn't work.Digital clock does not work. Lights on the console shifter don't light up. Help!

Instrument Panel Fuse Block
The instrument panel fuse block access door is
located on the driver side edge of the instrument panel.

Pull off the cover to access the fuse block.

The vehicle may not use all of the fuses shown.

Check your fuse box for a blown fuse first.1 fuse controls power windows and locks, not 100% that it controls the brake light problem. I believe it is fuse 14, check your manual for sure. If you dont have your manual shine a flashlight on your fuses and you sometimes can tell if they are blown.

Brake lights
there is an actuator above your pedal that activates when you press the brakes. I have had these go out on one of my cars, difficult to replace but cheap.

If none of this works then you will have to go to the dealer because they wont tell you what the codes mean.

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.
