Thank you for allowing me to assist with your problem.
Regarding your fuse issue, there may be a couple of things to look for...the first thing that I would look for is corrosion at the wiring harness connector under the bed that feeds the rear taillamps. Salt, water intrusion and the like can cause these contacts to oxidize, and the oxidation can spread across the teminals, shorting out to the ground wire in the same connector. Most noticible in the "snow-belt" states, or if you put boats in water. Check for corrosion in this connector, if it is OK, please get back to me for other info.

Had the same problem with a corolla. Turns out it was a turn signal/brake light bulb; the glass bulb had separated from the brass base and shorted out when I put the vehicle in reverse. Vehicle worked fine otherwise. Replaced the bulb, end of problem. Same idea as the corrosion of the wiring to rear lights.

Why does 4wd button blinks but front driveline moves. is the 4wd engagedon a 2004 tundra?

Probably because you have engaged the 4x4 on and have forgotten to switch it off. I have a Pathfinder and it does exactly the same. However, my Pathfinder light only flashed when in lower gear combination and the strange thing is you cannot really go faster, as the gear train is in low revolution and the engine in high revolution. So, to fix this unexpected problems that occurs (sometimes) when you've engages 4x4 drive while the front wheels are in a turned position - either left or right, is to put it in reverse after you've switched the 4x4 system off, straighten the front wheels and let it reverse a couple of metres. You should see the light disappearing, and you're now in two wheel drive. Put the selector in Drive and off you go. If the problem is not what I think it is, then it's best you send it to a dealership where you purchased the vehicle. Normally they're under a three year warranty, so you should get a free inspection.

2001 nissan frontier is blowing ignition fuses when you let out on the clutch in first gear and reverse

Hi Brent,

Wow! That is a dilema! The only thing I can think of is that there is possibly a wiring harness that is rubbed through and when the engine rocks when the clutch is engaged, the wiring harness is shorting to ground. If you can tell me exactly WHICH fuse is blowing I can possibly help you to locate the source of the problem. Please also include WHICH ENGINE your Nissan is equipped with and let me know if it is 2-wheel drive or 4-wheel drive.

I was researching the recalls for the 2002 tundra and havent found any recall pertaining to the 4whl drive. Sometimes when people have their 4wheel drive locked in and drive on pavement for any length of time, whether it be just a couple of feet or a couple of miles, over time it creates a binding of the gears in your transfer case. Once the bind is so great, the engaging and disengaging starts malfunctioning and leads to bigger problems overall. I could be wrong about this being the problem that you have but I think its something to look into. It wouldnt hurt to put your vehicle up off all fours and release the bind if any by running through the gears while in 2 and rour wheel drive while all four tires can move freely and release. See if that works for you. Check your gear oil front , center and rear and use much caution when attempting this suggestion. Also refer to your owners manual troubleshooting section for other possibilities. Merry Christmas. By the way, the electrical switch should be covered in the troubleshooting section also.

I have a 2005 toyota tundra with rear parking sensor that stopped working any trouble shooting ideas?

check the fuse for that circuit.there is a beeper under the dash as well.put a test light on it and see if it flashes,that means the beeper is dead.remove the switch if there is one that turns it off and jumper across it,and check the circuit from the shifter wiring to it,and also the reverse lights,they may have it wired to the reverse lights.

Toyota tundera v6 ran for fifty miles 2 quarts low on engine oil! dave

Probably didn't hurt it, my 2002 was ran for 2000 miles 1 1/2 quarts low on oil due to dummies putting only 5 quarts of oil back in it after changing the oil. It takes 6 1/2 quarts. It didn't hurt it at all.

02 tundra elect problemblowing fuses when in reverse/using left signal

Trailer? Am I to assume that you have a trailer harness? If so, that may be where your problem lies. Disconnect the trailer harness and plug everything else back together.
