You seem to understand test probe. Try a jumper around the AC switch on the dash. If it works with the jumper, the AC switch is bad. Or power supply to the ac switch is bad, a fuse in line to the AC switch maybe bad.

Ac not working, air compressor clutch not engaging


Hi Adeyeri

Keep in mind that the Clutch won't engage for a few safety reasons.

Temperature inside vehicle
Temperature of compressor or pipes
Pressure inside pipes
Compressor jambed
Eg It's out of refrigerant Gas

You can momentarily engage the clutch by simply giving it +12v to the wire attached to clutch. Usually has a connector close by.
Or
If it has a Relay (click) in fuse box
You can by pass it with a jumper

A quick engage & disengage should allow you to detect possible problem.
But don't over ride the built in safety for more than about a minute.

Cheers
Hope this Helps

High Beam headlights don't work, Taillights don't work, Brake lights don't work, Cruise control doesn't work.


Hi Harlan.

I see that you mentioned a 1999 Dodge Grand Caravan in your other question. I assume this question is about the same vehicle.

The checkup will start from the fuse and relay in the power distribution center. A way to test the relays is swapping two relays of the same kind to check if that makes any difference.
If relay and fuse are OK check the wiring to power distribution center, check the dimmer switch and the connection to BCM (the module under the dash).

I have uploaded relay map and wiring diagram at this link. Please click on the link. If necessary click on the picture again to enlarge.

Regards.

My fuel injector on my2004 nissan titan went out about 2 years ago. i went to a mechanic who got me a new one and installed it. 2 weeks later it stops again. i go back and he says its a relay, which nissan...


In the two years since it last worked the gas pressure could have fallen so now it won't work and wouldn't have worked if you hadn't borrowed the relay.

On average a vehicle air-con needs a top up every couple of years so I suggest you begin by visiting your local air-con service centre.

I got a 2004 chevy trailblazer 4.2l. DRL/lowbeams don't work. All other lights (park lights, high beams, turn signal) work. Driver side DRL bulb blew. Both went out at the same time. Replaced both...


If it is anything like my 04 GMC Sierra, there is a relay panel under the hood. In that underhood box where you found the fuses, there are also relays. They pop out (the diagram is on the lid of the box). After the GMC hit 200k, the relays started going out. The high beams are on a relay, the lowbeams are on a different one. You can pop one out and replace it with the horn or foglight relay if you want to check it out. I am betting that the DRL bulb just happened to go at the same time. Mine go out regularly..I would say around every 10-15k miles. I don't know if this helps, it is just something that I have run across with a similar vehicle.

Kia optima low beams


First verify that the switch is energizing the relay in both positions by turning the low beams on and then pulling up the relay--does it click? If not, replace the switch. If yes, next check for power on the red wire as it comes out of the column. Switch on, no power--replace the switch. If power, check for power at the head-low fuse in the engine compartment fuse box. No power--find break in wire. If power, check for power on the yellow/red wire as it comes out of the fuse box. No power--repair fuse box. Power--check for power at lamps--same wire. No power--repair yellow/red wire.
