pull the radio assembly out check to make sure that all your wiring is connected to the radio securly

Station Pre Set:
You can save 4 pre sets on this radio (1-4) tune the radio to the station you want to save then PUSH and HOLD one of the pre set butons until the sound returns, the station is saved to that pre set. Repeat for the 3 presets.

Clock:
Hour: Push and hold the CLK button and at the same time push the SEEK button to adjust. < decrease hours > increase hours.
Minute: Push and hold the CLK button and at the same time push the TUNE button the adjust. < decrease minutes > increase minutes.

Push clock button down and use seek and tune to adjust time

best bet is to chage your radio get a new one best buy has some good dual din radios

Okay, I'm assuming that you were sucessful in resetting your radio code.
I'm also assuming that you have a CD player (which may not be the case).
The flashing clock also functions as an error code indicator. It should say something, indicating what the error is. You can't set the clock until the error is resolved (a disc stuck in the CD player, for example, on no disc in the CD when it's been told to play).
The procedure is as follows (which you probably know):
The audio system display usually shows the time when the ignition switch is in ACCESSORY (I) or ON (II). It shows the operation mode of the radio, cassette player, or optional CD player/changer when you operate them, then goes back to the time display after five seconds.
If an error occurs while operating the optional CD player or changer, the display will keep showing the error code and will not switch to the time display until the error is corrected. You can set the time only when the clock is displayed.
To set the hours, press the H (Preset 4) button while pressing the CLOCK (SCAN/RPT) button. Press and hold the H button until the hour advances to the desired time.
To set the minutes, press the M (Preset 5) button while pressing the CLOCK (SCAN/RPT) button. Press and hold the M button until the minutes numbers advance to the desired time.

If you don't have a CD player, or no error is showing in the clock read-out, leave a comment so I can investigate further.
Hope this helps you.

Need to have the key in the accy ( or run ) position.

On the Cassette version, there is a CLK button on the right side of the radio face, press this, and then use the seek button to increase / decrease the time. Pressing CLK again takes it to the min setting, Do not press a button for 10-15 seconds, and the display will return to normal.

single CD, CD changer, and Cassette /CD changer versions, the RDS button is what is used to get to the time setting, using the select button to change the hours, press RDS again to get to the min.

sorry radio is bad replace wu=ith one from a junkyard
