2004 Chev SSR top want go down, say top in time out


The first thing to do would be to hook up a scan tool that can communicate with the Roof door module (RDM) an check for code's (DTC'S) . Can set a bunch of different code's

DTC BThe roof door module (RDM) checks the outer latch latched signal circuit, at least once every 200 milliseconds.
The folding top outer latch position switch is supplied with a constant ground source.
When the switch is active, the RDM will detect a switched ground signal on the folding top outer latch position switch latched signal circuit indicating that the latch is latched.

DTC B3685
Without a factory or professional scan tool you can't read these code's . Advance , auto zone , pep boy's etc .... can't read these code's . Your best bet take it to the Dealer or someother qualified repair shop.

Does your vehicle have three or four button shift switch ?
The NVG 236 transfer case features a 4 button shift control switch located on the instrument panel.
OR
The NVG 233 transfer case features a 3 button shift control switch,
The transfer case shift control module is equipped with the ability to store diagnostic information, which is useful to a technician in the event of module, component or wiring failures. This information can be retrieved from the transfer case shift control module by way of flash codes, which are displayed on the three transfer case shift control switch buttons. These buttons are located on the instrument panel to the right of the steering wheel Before obtaining DTCs, perform the following transfer case control module (TCCM) Self-Test.
TCCM Self-Test
Observe the transfer case shift control switch indicators while turning the ignition switch to RUN. A properly operating system will flash all indicators and then will return to the current gear. If the system is operating normally, then proceed to Displaying Codes.
If the TCCM failed the Self-Test, then test the following circuits.
• Battery Positive Voltage (40 and 1640), and Ignition 3 Voltage for battery voltage
• Ground Circuit for ground
• Diagnostic enable circuit for an open or high resistance
• Transfer case shift control switch connector
If the above circuits are normal but the TCCM still fails the Self-Test, replace the TCCM. Refer to Transfer Case Shift Control Module Replacement .

DTC Displaying
Turn OFF the ignition for 10 seconds.
Connect PIN 13 on the data link cable (DLC) to a ground. The DLC is located in the cab under the instrument panel on the driver's side.
Turn ON the ignition, with the engine OFF.
Observe the transfer case shift control switch select buttons for flashing codes. Refer to Diagnostic Trouble Code (DTC) List .
Important: If the transfer case shift control switch buttons all blink only once and then stop, no fault codes are stored in the transfer case shift control module.
• When one DTC is stored in memory, that code will blink that number of times followed by a 3 second pause and then repeat.
• If more than one code is stored, the first code will blink, followed by a 3 second pause and then the second code will blink.
• This sequence will continue until PIN 13 on the DLC is no longer grounded.
• If the TCCM will not communicate the presence or absence of DTCs, test the above circuits in Self-Test Step 2. If the circuits are complete, then replace the TCCM. Refer to Transfer Case Shift Control Module Replacement .

The four button switch system is a bit more complex ,need a factory scanner or professional one to check DTC'S

DTC C0305
DTC C0308
DTC C0309

DTC C0327
DTC C0362
DTC C0367

this is where you should start ,checking code's .

How do you reset the security light on a 2005 chevy cobalt?


There is no reset , if security light is lit there is a problem with the anti-theft system .Should have it checked for DTC'S - diagnostic trouble codes . Could have 8 different B - codes
DTC B0685 DTC B2955 DTC B2960 DTC B3031 DTC B3033 DTC P1626 DTC P1630 DTC P1631
You would need a professional type scan tool to read these type codes , not an OBD 2 code reader .
