Radio has no power - 2003 Toyota Sequoia

The fuse you want to check is the F1-17 fuse in the battery junction box. This is the radio fuse.
The number F1-17 fuse is the red/yellow power wire at the radio. If the fuse is good pull the radio and check the red/yellow wire for power in, if you have power in , then suspect a bad radio.My next step would be to remove the radio and check the power wire going into the radio (red/yellow) . If you have power there, then the radio is likely bad. Ford has had major problems with the radios.

does the power antenna sense the power lead of the radio . Did you somehow disconnect a sensor wire from the radio power wire when installing the new radio.
This might be the cause of the power antenna not going up when radio switched on ?

there should be 2 power inputs in radio connector,1 for radio power other for memory. If you have both then radio would have to be sent out for repair.

got a voltmeter,
make sure the ground wire is 0volts , key on, radio on.
then make sure all 12vdc power wires, on radio have 12vdc.
some have 3.lines. (and a 12v out to antenna motor (skip that)
radio power, memory, and dial lamp.
the radio power must be hot. or radio will be DEAD.

it's that simple , any DMM even the dirt cheap one at walfart does this.
the meter will never lie to you, and can also check your bad fuses.
0 ohms good'
infinity ohms bad fuse.
easy huh?

It can be faulty radio amp or radio control fuse is blown out.Check voltage at radio wires.You should get 12 volts.

These details will help you thanks.

The fuse you want to check is the F1-17 fuse in the battery junction box. This is the radio fuse.
The number F1-17 fuse is the red/yellow power wire at the radio. If the fuse is good pull the radio and check the red/yellow wire for power in, if you have power in , then suspect a bad radio.

My next step would be to remove the radio and check the power wire going into the radio (red/yellow) . If you have power there, then the radio is likely bad. Ford has had major problems with the radios.

You have to remove the radio and check the power going into the radio to make sure it is getting power. There is an internal radio fuse which you can't check without taking the radio apart. Likely the source is the radio. Checking for current to the radio will determine if the source is the radio or not. If radio does not power up, antenna will not rise.

There are 3 fuses in the interior fuse panel that feeds radio.
no. 11(10amp) is ignition switch power to the radio it comes into radio on the TN/LB wire.
no. 27 (10amp) is hot at all times and comes in on OG/LG wire.
no. 12 (5amp) is hot in run or accessory and comes in on YE/BK wire.
Check these with 12V test light at fuse and at radio connector.

There are two fuses that power the radio. The 15 amp CIG fuse and the 15 amp DOME fuse.
AT the radio connector, you should have 12 volt power in the GREY wire (this is the main power from the CIG fuse) and 12 volt power in the BLUE with YELLOW tracer (this is memory power from the DOME fuse). If you have power in botrh of these circuits, suspect the radio being bad.

u need the colors of the radio or the car wires.... here are the car wires and the radio are below that. I suggest however gettiing a wiring kit..They are around 8 dollars and well worth the money. It makes is so easy to connect a radio.
RADIO 12V|orange + at radio
RADIO GROUND Black
RADIO SWITCH yellow
POWER ANTENNA dk. green at radio LF SPEAKER tan - gray at radio or LF speaker
RF SPEAKER lt. grn - dk. grn at radio or RF speaker LR SPEAKER brown - yellow at radio or LR speaker
RR SPEAKER dk. blu - lt. blu at radio or RR speaker

Radio wiring
constant power yellow
switched power red
power antenna/amp turn on blue
illumination is orange
all speakers the one with the black stripe is the negative connection.
right rear is purple
left rear is green
left front is white
right front is grey

hope that helps ya...
