I would take it to a parts place that offers battery/alternator testing services and let them do a load test and test the alternator/battery charging if possible.

I agree that this is probably a regulator issue.

However, I would like to add that if you are experiencing these problems, to not use the AC/fan as the climate control module could get damaged by a varying swing in voltage.

Post back and let us know if the turn signals work or not before you try to disconnect and what (if anything) changed afterward.

Here is a thread that can help with AC issues
..and here is one specifically for the jump start.

As for the turbo I will have to defer to others in the forum. I would suggest you check your hoses for dry rot/etc, just to rule out any of those.

hope this helps.

It sounds like you have a problem with the steering wheel module. Does you turn signals and wipers work properly? Are the functions dead at all times or intermittent? You might be able to get them to work "temporarily" by removing/replacing the fuses for the swm/cruise/turn signals or by d...

If going to advance is a "short" drive, then I suggest you take the car and ask them to test the alternator (and battery again). They should be able to run a simple test to verify the voltage output of the alternator. A short distance drive does not sound the same as your previous trip sta...

This definitely sounds like the voltage regulator. Unfortunately, most chain parts stores don't sell just the regulator as it is an internal component of the alternator (with the brushes attached). If you can find an alternator/starter shop in the area, they can get you the voltage regulator and may...

It is not hard to replace, but you have to be aware of how to handle the airbag...Here is a post that directs to a write up that outlines how to remove the airbag/steering wheel..once you remove the wheel you have a plastic cover to remove and then you can get to the controls and then to the module....

Bart, To follow up on the CCM issue, I had to have the module programmed at the dealer to have it activate the compressor/etc properly. Also, you will notice that once you install the "new" one, that none of your auxiliary buttons work...the programming activates those as well. Lastly, if ...

...Went to an other Volvo dealer and they checked the output on there computer and rebalanced the system,right side will become cooler after 10 min. on a hot day,they say it may have a defective control motor that controls the flaps for the right side.. Will let you know how that works out.???? Esn...
