[quote=”nightflyr” post=189006]Possible causes:
Faulty pressure switch or connection ( if equipped )
Faulty pump
Faulty steering rack[/quote]Thank You for stating the obvious. I was hoping for more specific answers that would help diagnose the problem and narrow down what to replace. I was hoping to hear from someone that has experienced the problem, or has dealt with it in the past.
Thanks for your reply grouchy-hermit. I personally change out my brake fluid around every two years, however I can not go by that. I do general maintenance on a couple of limo fleets as well as on family, friends and neighbors vehicles, totaling to around 100 vehicles in all. I also take care of most brake system problems. I am not a trained mechanic, but a diy’er that happened to pick up some side work that turned into something more.
I personally would not use brake fluid that is two years old once the seal is broken, I wouldn’t even use it after a year. So my question still stands, How long is a container of fluid good for once the seal has been broken. At this time, I won’t use a bottle that has been opened longer than a month, only because I don’t know what the shelf life is after the seal has been broken. If the fluid is still safe to use six months later, then I won’t have to by so much and waste it.
On Barbara’s Town & Country, the refrigerant capacity is 46 ounces for vehicles with front and rear AC. For vehicle with only front AC the capacity is 34 ounces. You did not have enough refrigerant to handle the load, which is why the system was not cooling properly when both were operating. When you shut off the rear, then the system was able to do its job because of less demand.
