Ctsy fuse keeps blowing

2o amp cty fuse which,from the research ive done, helps to work dome light, door sensors and radio. not sure if this helps but have an alarm hooked up to door sensors (used for dome light) and so not sure if that is causing a promblem. also have subs and amp hooked to radio but fuse on radio not blown. unplugged radio harness and tried a fuse and still blew it, unplugged dome light bulb and still blew, so that mean it the alarrm system, or just wiring for door sensors/

    okay well thank you for all the great ideas fr a solution but i ended up figuring it out actually. so at first i was thinking it was the ground or maybe short in alarm or a wire somewhere, but i went and tlked with a dude at audio express and he said the same things about the ground and mentioned maybe a problem with cig light whether it be a wire or something, but then he also gave me some very important info about how on a car they had they tried for hours trying to figure out what it was and the guy had the same prob, well come to find out some change got stuck in cig lighter and was causing it to ground and so instantly causing the fuse to blow. sure **** that was the case with mine. a penny had acidently got in the cig lighter causing it to ground, a fuse and penny richer, the problem was fixed. lol

    Matt Day. You are a blessing for posting your solved issue on here my man. I was have trouble with courtesy fuse, repetitively blowing fuse after damn fuse, after installing the two cargo lights my 1994 GMC Sierra has... I've been stressed to the max the past week, with not being able to play my aftermarket radio w/ subwoofers (since the radio is tied into the courtesy fuse circuit) not too concerned with my dome lights and floor lights... After reading your solution, I remembered I put a push style cigarette lighter I found in a junk yard in it (I figured would be convenient to be able to use) sure enough it was a different style of one, causing it to ground out my circuit. I took it out and replaced the fuse with no more issues!! Thank you again for your stress and money saving time putting your solution on here!

With Dome Override button Out, dome light will stay on approx 1 min. (after shutting doors) before automatically shutting off. Make certain that courtesy light wheel is not rolled all the way up. This keeps dome on constant. Dome light override pushed in keeps dome off when opening doors.

SOURCE: my 96 blazer keeps blowing gauge fuse which is a

This is serious current flow and way way over what should be flowing in the circuit. You have a dead short somewhere which is likely to be beneath the dash panel. possibly the printed circuit board behind the instrument cluster.There may be something else sharing the fuse too which has the problem and not in the fuel gauge at all.

SOURCE: clock, and dome light (2004 aveo)

If the fuse blows when you start the car their is a bare wire somewhere in the wiring system that is grounding out when power goes through the system. Thier is a possibility of it being something else that is on the same fuse. You will have to trace the wires to find out what and where it is exposed. Your switches should be tested also. The switch that turns the light on manually and the one located in the door jam itself that turns the light on when opening the door. You should bring your car to a mechanic who is qualified in electrical dianosis. I hope this helped you out. good luck..... It would be appreciatted if you could rate my answer. tThanks....MIKE-

SOURCE: Security Light always on, door lock fuse keeps blowing

This is most likely a problem with your Passlock anti-theft system which is known issue with these cars. Passlock is a "passive" anti-theft system, which means that it will disable your ability to start the car if it thinks there is a problem. The three components that can cause this are: 1) Ignition Switch, 2) Ignition Cylinder, 3) Body Control Module (computer). The dealer is the only one who can solve this problem (unless you can bypass it, but it is not that easy). Estimated repair from most dealers is $800 and up.

99 malibu inop radio fix

Stock radios have 2 fuses that run them.

Fuse 1 is usually labeled as Radio in the fuse box.

The 2nd fuse shares circuits with other devices that are powered straight off of the battery, so look and see if your dome light works, and your cigarette lighter. If either of those aren't working, check the fuse for that item. Cigarette lighters are usually listed as Cigar in the fuse box, and dome light is usually CTSY or Courtesy.

The interior lights will not come on when door opens, the visor lamps will NOT light no matter what, radio lights work normally the turn signal lamps blink fast, but all bulbs light

For the turn signal flashing fast - MAKE SURE you have all bulbs flashing that are SUPPOSED to be flashing. The front side marker lamps are part of this equation.

As for the interior (dome and visor) lamps, there is a fuse labeled "CTSY LAMP" in the fuse block. The lamps themselves are controlled by the body control module (BCM). The CTSY LAMP fuse only provides input power to the BCM. I would start with a scan of the BCM to see if it can shed any light (No pun intended) on your problem.

I have a 1989 chevy s10 horn radio and dome light not working keeps blowing horn/dm fuse out

Check inside the drivers and passenger side door jam for the little push in type switch. 9x out of 10 one or the other will be causing the short to the dome fuse. These little **** get rusty and also get alot of wear and tear from the door opening and shutting over and over. These switchs are what causes your dome light to come on when you open your door and or likewise they shut your dome light off when you shut you door. A very good way to test to see if one of these little switchs is the couprate is to take and hook up a voltage light into the negative side battery post after you disconnect the battery negative line.. If your voltage light is on than that would mean that you have a short somewhere in your system. Now, since you already know that you are blowing the dome fuse then your already halfway there. With the light on your votage light still on indicatin a short, unscrew the little switch on the door jam and disconnect the power wire from it. Check to see if the light on your voltage light is still indicating a short, if not then you can be sure that the door jam was the coulprete. Hope this is of help.

Fuse labled ctsy what does it service

Hello swatem1: My name is Roger and I will help. You did not specify a specific year car you were looking for. This is for a 1988 thru 1991. They do change things from time to time. The ctsy fuse carries power for the inside lights,power antenna,automatic safety belts (1991) and the warning and alarms (1991). Should you need more specific to d different year please just ask. Please rate the answer. This way I know it was helpful. Thank You for using Fix Ya. Roger
