I have problem with remote control, my remote control gives me blue light to switch the dashboard on but there is no lights coming on the dashboard. what is the problem


Hi, your remote has probably lost its coding. If you have the owners manual check page 65 learning additional remotes. If not do the following 1. Plug in the 6 pin hopped coded plug to control unit under drivers seat. 2. Press unlock button twice to disarm. 3. Press learn button on hopped coded plug. this erases all pre learnt codes. The led on dash should start blinking once per sec. 4. Press learn button on hopped coded plug again. The led on dash remains on for 4 sec. and then starts blinking faster. Ensure to do step 5 within 25 sec. 5. Press any button thrice on your remote that has a problem. 6. In response led on dash remains on for 4 sec and then blinks once per sec.This indicates that the remote has been learnt. Hope this helps.

When i press the 4x4 switch it blinks along with the 4 low switch the goes back to 2 high sometimes i can get the 2 high to work but not the 4x4


What type of vehicle is this? I'm assuming you have a part time transfer case with the 4h,4l and 2h selector switch.
Without knowing the vehicle I can't be certain, but the problem you are describing sounds like the Encoder Motor on your transfer case has gone bad.
Can you hear any noise when you try to select a gear range?

Transfer Case Shift Control Switch Indicator Flashes and Returns to Original Mode.
Circuit Description
This symptom usually occurs when a shift into or out of 4LOW will not occur. When the transfer case control module (TCCM) receives a request to shift into or out of 4LOW, the TCCM must see the following parameters before the shift routine can start:
?€¢
The vehicle speed must be below 3 MPH.


?€¢
The transmission must be in neutral.

If the TCCM does not see these conditions the shift control switch indicator lamp will flash for approximately 5 seconds and then return to the original gear.
Test Description
The numbers below refer to the step numbers on the diagnostic table.

  1. This step tests the operation of the transfer case shift control switch to help determine if the system is operating properly.

  2. This step determines if the vehicle speed sensor reading is correct.

  3. This step determines if the park switch reading is correct.

It could be a junk switch or it could be bad contacts inside the transfer case motor.. Does the transfer case switch to the selected gears? Everytime? If so, you might try another switch. If it does the same, I would say the motor contacts are bad. Replace the motor if you want the lights, But I personally wouldn't do it until the motor quit switching gears. They're not cheap.

2007 chevy trailblazer won't go into 4 wheel drive


Have you had codes checked ? While connected to a good scanner that will check transfer case switch to show if switch is working, and it could be the switch on the side of the transmission.

Will not go in 4 low 4x4 lights start blinking after trying . reset light by unhooking battery . then goes in 4 high normelly but not 4 low. i thlnk auto 4 is working 4 liter SOHC 1998


Normally 4 wheel drive HIGH is engaged on the fly or as you are moving more than 10 km per hour or 10 miles per hour but 4 wheel drive LOW is engaged at around 3 to 5 mph. no more or you could ruin the transfer case. Try going from 2 high to 4 high by switching back and forth and then try 2 high to 4 low when idling along. What usually happens is the mechanics under the car freeze up or rust up and you have to switch back and forth to free it up.

My transfer case is permanently engaged but no 4 wheel drive...


2 common problems that cause this are the vacuum switch on the transfer case and the vacuum actuator mounted under the battery tray. When the switch on the transfer case goes bad it pulls fluid out of the transfer case and pumps it into the actuator and destroys it. The switch only costs about $15 and are usually stocked at major auto parts stores. The actuator ranges from about $50 to $120 and most of the time need to be ordered. If you reach under the battery tray with the 4wd engaged and follow the cable you will feel the end of the actuator, make sure that it is pulling back. If not either the switch or actuator or both are bad. Hope this helps.
