99 Infiniti I30 - random issues by jeni_a_m
Sep 14, 2009 (11:18 am)

I took my nearly 150,000 mile car to this terrible mechanic because the car kept dying, no warning it would just die. Got a new battery and a new alternator but no luck. They said it must be electrical. So after 2 days of them "fixing" it, they said it was a fog light that was bad, they unplugged it, and I was good to go. Well, it runs but now I have the most random issues. First the remote didn't work, turns out they didn't plug back in the wires in the trunk, so i fixed that. Now the air conditioner will blow on full for awhile, then self adjust to low and go back in forth, although the fan meter says it's on high the entire time. When it's 103 out, I really need it to work. The other issue is the radio will work, then the front speakers will cut out and then come back on...over and over. PLEASE HELP!!!! I won't take my car back to that mechanic and I'm being quoted $100 for anyone to even look at it.

I'd take it to the dealership, where you know they would have the electrical skills, schematics, and any test equipment for your model.
 
The hardest problems to find are randomly intermittent ones. Your radio and a/c problems sound like they occur fairly regularly, so they should be easy for a good electrical guy to zero right in on the problem.
 
If the fog lights were factory, hard to imagine they would create some sort of electrical problem that was causing your vehicle to die. If someone else installed them aftermarket, then no telling what they did to the wiring to get power.

Thank you. I will most likely have to do that. I'm sure the genious that worked on it didn't plug something back in very well, but like you said, without that knowledge there is no telling what it is.
 
They are factory lights, but for some reason the light case will hold water. I guess there is a crack or something, but I can't see it.
 
I'm trying to keep the car going for at least another year, but I was just told the radiator has a hairline crack and the cad. converter is going out. I do the regular maintance, and I know it's a good car, I guess the one I bought just isn't wanting to hold out.

Water in the light, should have caused that circuit to short out, which should have caused a fuse to blow.

Blown fuses by bbpar117

I have dashboard and tail lights that blow fuses at least 2-3 times per week. They both share the same fuse. The signal lights continue to work even when the fuse blows. What type of problem would cause this?

Someone would need to know your year/make/model, and then have electrical schematics to review.
 
But without that info, I'd suggest checking the taillight bulbs for proper operation. Brake lights turn on the high intensity filament in the bulb, headlight/running lights turn on the low intensity filament in the bulb.

Fuse Panel - 2000 Buick Century by 2000buickrehab

Hi all, I own the Regal's twin, the Century, but there seems to be more activity here than over at the Century forum.
  
My Century has some issues that you may know how to resolve. The twin cooling fans will not kick on, I checked the battery because of the low voltage safety feature, had a dead cell in a <2 yr old battery, replaced, but still no fans. I can jump straight off the positive to the white fan on the right side, the second fan will not kick on even with a hot feed. See next posting for the rest.

Fuse Panel - Buick Century 2 by 2000buickrehab

The A/C will not engage, the odometer and (PRNDL) will not display, intermittent failure of the "lock" feature on the door and via remote keyless access. is there a relay, ground or inline fuse between the power supply and fuse panel for these lines that I should be looking for?
Plan on pulling the Cluster to look for a bad relay/resistor/fuse/bulb, but there seems to be a bigger issue. See next posting for the rest.
