Q: off road welding inc wrote help our shop recently extended a mega cab. when the truck is running the flashers and blinkers do not work!!! however when the truck is not running they work fine !!!! keep in mind we touched nothing electrical and disconneted all power when welding. thanks the first thing i would check is the flasher control unit. its a computer circuit. it may have been damaged by the welding arcs. jam .

might i suggest measuring the actual discharge temp of the hvac system before proceeding further doesnt seem as warm is too subjective for me to warrant the time and expense of blend door surgery. thats the reason for the disclaimer at the end ^ awright already!! i missed the disclaimer the first time..... sheesh.... ;^ mike .

my very first truck was a dodge 1979 sno-commander. it was full time 4wd. thats why my husband called it back then. we never had to do anything to put it into 4wd. he since passed on and i finally had to sell that truck and i bought a dodge 2003 1500 with 4wd. except you have to shift the transfer case into 4wd when you need it. i only need 4wd for plowing my driveway. fairly flat/level driveway. i have no problems plowing. is there any difference between 4wd-h and 4wd-l on the transfer case shift lever i know that one is used for intance if youre already out driving on the road and want to shift into 4wd. my question is - do both the h and l perform the same thing when the truck is in 4wd yes they do. the only difference is that 4wd-l has an increased gear ratio for a significant increase in pulling / pushing power at a significant reduction in speed. in your case 4wd-l would allow you to plow your driveway without cooking the transmission. the only real difference is that you cannot shift into 4wd-l while the truck is moving and the gearing is way to low to drive it at any speed in 4wd-l. another question is why is there some tire spinning/slipping when im navigating a sharp turn from the back of the garage around to the side garage in driveway on paved surface. the truck is barely moving because its a tight turn. my 1979 never did any tire spinning. do they make 4wd trucks weaker than they used to it has nothing to do with the strength of the system but rather the implementation. a full time 4wd has been set up for use in all conditions and has a method to allow the front and rear axles to turn at different speeds such as in a turn. a part time 4wd is designed for use only under slippery conditions reason its called part time and simply locks the front and rear axles together. it depends on a wheel slipping under a tight turn to make up the difference between the axle speeds during a turn. because of this part time 4wd should not be used in dry conditions especially during tight turns as the increased traction of the tires in these conditions prevent them from slipping easily and put excessive stress on the drive train and this can damage it. the last question is while driving on a stone/dirt road that is just at the start of driving up a mountain near a ski resort in the finger lakes in ny......i began in 2wd and felt it needed 4wd. i put it in 4wd but it kept popping out and into n. i finally had to cram it in 4wd and keep holding it while driving up and up for about 2 miles before i got to my friends house. then it was another .25 mile up their driveway. is that a common thing that the gears wont engage actually my grandam navigates that road better than the truck. it is not a common thing for it to keep jumping out of 4wd. as said before part time 4wd locks the two axles together and is not intended for use on dry roads. this locking of the axles causes wheel slip in turns which may make the truck feel loose on dirt and stone roads especially compared to your front wheel drive grandam. as for it jumping out of gear that is not normal and indicates a possible defect or damage to the transfer case possibly from engaging the 4wd in dry conditions during tight turns. i would have that looked at. -- if at first you dont succeed youre not cut out for skydiving .

since power = volts x amperes; an increase in the applied voltage will result in a proportionate increase in current and an increase in the power that is a *product* of the two. an increase in consumed power will cause the filaments to burn hotter and reduce the life of the lamp. another factor is the number of on/off cycles. a lamp filament undergoes an extreme change in temperature from off to on causing a mechanical stress in the filament. these mechanical stresses in the filament decrease the life of the filament. bryan steve lusardi wrote most likely higher system voltage. this will be a product of the voltage regulator on the alternator. you are probably over 14 volts when running. steve nunya wrote just had a headlight bulb burn out in my 97 ram 4x4 this weekend. i went ahead and replaced both at the same time as usual. as i was logging the service into my service journal i looked back to see when the last time the bulbs were replaced on this truck. at 275350 miles and 10+ years of rough service this is the first time i have ever put new headlight bulbs in the truck. i was amazed the factory bulbs lasted a decade. i decided to look at the service records on my other dodge trucks. the 2001 3/4 ton 4x4 diesel at 160k is still on the factory bulbs. the 1991 dakota that has 177k known miles had a broken odometer for a while is on its 2nd set of bulbs. the 1993 4x4 dakota with 220k is on its 5th set of bulbs. i am now curious as to why the 93 goes through so many more bulbs than the others. any theories michael .
