Question: Unsafe Electrical Issue

2000 Volvo S40 Electrical Issue: my car recently started to lose all power and stall while I'm running the A/C. It only happens when I run the A/C and never when I'm not running it. The car only stalls at low speeds or in park. If I let the car sit for 10 - 20 minutes, the power will come back - odometer, clock - and I can start the car with no problem. Could some bad wiring be tripping a circuit breaker that is killing the power to the car??

I have had my car in to the mechanic twice in the past 2 weeks and no one can figure out what is going on.

I noticed this issue happening when my car stereo (original, stock) started to make clicking sounds this past month from the tape player as if a tape is being inserted into the deck. The stereo makes this clicking sound even with the stereo power turned off AND when the car is turned off!!

I fear that I'm going to get stranded with my children somewhere due to this issue.

If anyone has had a similiar issue, or a mechanic can advise me on this it would be greatly appreciated...

Thank you!

Sounds like a problem with the main relay or maybe the ignition switch? Hard to say this is a strange one for sure.

Also check the grounds and battery connections. Check the engine and transmission computers for any stored fault codes.

If this doesn't help, you could try removing the radio and seeing if that changes anything or that noise goes away. The sounds might not actually be from the radio but some relay under the dash.

Good luck

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
