Q: I had a heater core leak and changed it. After a good days work of tearing the dash out and all I had it back together and cranked up the Jeep to ensure no leaks, Turned the Heater on after a few and the blower was not working. Took another day of back tracking to make sure I didn't miss anything and still no blower. I have checked the fuses and even changed the Resistor still nothing. What else could it be, I know the fan is good as it was working before, the switch also never gave me a problem so I would assume it is good also.: I've heard of a lot of issues with the blower switch in your vintage Wranglers, but you can spend a lot of $ throwing parts at it hoping to find the fix. Best bet is to get an electrical multimeter and a manual and start testing. A good manual (maybe Haynes or Chilton) or better yet the Factory Service Manual will outline testing procedures for each component.

Q: I have a 2003 Chrysler Sebring. When I first bought it, six months ago I replaced the fuse that powers the radio, trunk button, unlock/lock button, and rear view mirror light. I replaced it every two months but lately Ive had to replace it every other day! I have no clue whats going on or what I should do. Please help!: is this an OEM radio or an after market? do you have an Amp on the same circuit? Look at the power requirements for the raido if this is an after market, it may take more juice than what the fuse can deliver. *************************** DO NOT replace the fuse with a larger amp fuse. your car can catch fire because you just over loaded the circuit **************************

Q: I have checked every single fuse under the hood and under the steering wheel. Still no radio, clock, or dome lights.: Double check the fuses tor the dome light and cigar lighter, its easy to miss a bad fuse If you have a test light or DVOM (multi meter) use it to check both sides of the fuse for power, obviously an open in the fuse is going to cause one side of it to have power and not the other. You will need these tool to verify the fuse is getting power, check the condition of the fuse, and trace the power to the individual components on that circuit. For backyard mechanics, Harbor Freight has these tool for the $5-10 range that work great for occasional use. Good luck man! If you need any further help with open / short diagnosis just let me know.

Q: I have a 1999 Mitsubishi Galant ES. The fuel level and RPM gauge will not work at all. I tried changing them out with the same result. The fuse for the gauges is ok. All other lights and the temp gauge works. Thanks: Double check the fuse box. You may have checked the fuse that list the gauges, but there could be a second fuse running those 2 gauges. It might be listed under the fuse but behind some other components that that fuse also runs. If not, I would pull and check all fuses in case they didn't list it right. Also there maybe a second fuse/relay box under the hood. Check that too.

Q: I found a 2x12 Line Six Spider III amp for sale, the vendor claims that it can be fixed by installing fuses. Does this mean that the current fuses are blown, or that it never came with fuses? In the former case, how would I be able to tell if the fuses are blown, or if it only needs new fuses and there's not some other underlying issue?: If a 25 cent fuse was all it needed the seller would have already replaced themthink about it. I would run awayfast.

Q: If I were to connect an appliance to something other than an electrical wall outlet for power and that device produced more volts / watts than what my appliance needs to work, would it mess it upand if so how to I control this?: if V I R, you are effectively increasing V while keeping R constant; so I through the device must increase. Power dissipated by the device I^2 R : so by doubling the applied voltage, you'd quadruple the power dissipated by the device. If you're lucky and the components can handle the additional heat dissipation requirement, then nothing will happen except the device will become quite hot to the touch. If the components can't handle the additional heat being generated, the device will burn out. If you're lucky, there is a single fuse or component that will burn out and break the circult; stopping the flow of current. If you're not lucky, then the device could continue to heat up and eventually catch fire. you need to buy/acquire/build a voltage converter/power supply -- something that will take the input voltage and current and output the voltage'/current required by the device. Running 12V electronics from a car lighter socket, you encounter this all the time. The DC adapter basically takes the raw 12.6V and ensures that the voltage/current specification required by the device are met.

Q: Hi my first visitI have been having problems with battery drains lately. Overnight the voltage of my car battery drops from 12.4 to 11.8 and if I leave it more than 3 days it will not start (11.5 to 11.2). On idle and load it is near 14.2. So I feel alternator is charging well.I am about to start pulling fuses to locate drain but was wondering if an alternator that is starting to die (but will still charge) can cause battery drain. Can the diodes in alternators draw current from the battery?Thanks: full charged battery's are 12.4- and up not 13.8 only, that guy sounds like a rude know it all. and yes it can, there are allot of thing inside the alternator that can go bad and drain the battery. if you want to do it the easy way get it tested at an auto parts store, they can tell you. if you would rather do it your self, use to volt meter and pulling fuses, but I suggest putting it on the amps setting and use and use the ground post and terminal. because if you accidentally ground out the positive side you could blow fuses, cause shorts, other kinds of damage, or get shocked. but of you ground the ground. well you'r grounding a ground and nothing happens lol. and don't let people tell you that you have to go to collage to change it or rebuild it. if you look the info up and just put you'r head into it there is no reason you can't do it or at least try. people that tell you that are just smart mouths and the world is full of them. my brother didn't go to school to weld and he is the best welder in this town and my uncle is a very respected mechanic and he didn't go to school for that either. I'm the first man to go the collage in my family and i still have to ask the older people around for advice allot. all school is, is a way to get a peace of paper, take it from me, there was some people in my class that would do more damage then they fixed. and they graduated too. anyways Hope you get it fixed.

Q: hello i have a short in my car the keeps blowing my ingnition relay fuse and i cant find it. no matter how hard i search. have any of u used one of that short circuit finds like this page describes Tech and if u did is it hard to use and how do you use it? i dont wanna spend $50 on junk.: An induction short finder shouldn't cost $50 around for a less expensive alternative. These work very well in locating the shorted circuit and generally will pretty much pinpoint the area where the circuit is actually shorted.

Q: I checked the cooling fan fuse underneath the hood but it is fine, i think that is for the radiator.There is 20 fuses in the hood fuse box. In the interior fuse box there is 25 fuses but my owners manual does not state any mention of an a/c fuse. What # is it?Where is the fuse for the air conditioner?2002 honda civic sedan.: both fuse boxes will have a/c components, and not just fuses. there are also relays

Q: Hi I never used the cigarette lighter in my Lexus es300 1993. . i recently bought a car cell phone charger and it doesn't work. I pushed in the cigarette lighter and it did not heat up. I replaced the fuse and it doesn't work.any suggestions will helpthanks so much,ALex, nyc: more than likely it is a fuse. Escorts that year have 2 fuse panels. one in the passenger comaprtment and one under the hood. when you take the sheild off for the fuse panel there will be a diagram explaining what all the fuses are where they go and what the amperage for the fuse should be. At that point find the fuse for the 12A power out, or 12A accessory ( or something to that effect. then i would replace that fuse. its your cheapest bet. If that doesnt work i would recommend replacing the element itself ( what you plug the lighter into). it also could be the lighter but advanced auto carries them as a set for like 20 bucks. good luck
