With this cold snap I had to replace my battery in my 98 PA, radio held its code and all seemed fine. Issue is every time I start up the dash says washer fluid empty, coolant low, tire pressure low. All of which are fine checked and rechecked, I am assuming the computer is not happy what should I do???

How many re-starts since you installed the new battery?

have you given the new battery time to charge? have a charger so you can charge it?

Hi the battery has been in the car two weeks with about four 70 mile round trips to my other half'* job, she freaks about the messages.

Phil

you can try to hold the reset button with those messages showing. i know it works for the oil tires and fuel. not sure about the rest.

Tried holding the button, tapping it etc nothing seems to work. I am going to see if the car shop by me can reset the computer.

When I changed my battery/alt, I plugged into the OBD2 port with battery saver cord to a power box. By the sounds of what Phil is going through, I am glad I did.
I know when the tires got rotated, I had warning, and had to hold reset for 10+ seconds in.

I had my local shop clear the computer, the oil light quit but the washer fluid is still flashing, may be time to just disconnect it!

i believe if you disconnect it, it may still give the same problem. if disconnecting it does not work, i would try and replace the sensor. there may have been a surge.

art, since we drive american cars and the sockets are always hot, using a 9 volt battery to an old charger plug works just as well. whenever i swap a battery thats what i do. saves you from finding a stereo code and doing presets and what have you

Jason, I have disconnected the PA without any battery saver with no ill effects other than the radio codes, seat etc memory & transmission doing a re-learn.
So in my next statement having any back up system is better than none at all.
So for those that may not be fully informed, I will present some info about the differences between the 9v and the OBD2 saver cord.

With the 9v approach, you must still ensure that the battery u are using is good & that the accessory socket is actually working live, and ensure your connections make consistent, reliable, contact /dont move or fail in that process.
In a shop environment or where other parties may be involved, simply by popping the trunk or opening a door, the 9V battery wont be able to handle the load.

For $15 -25 $ the OBD2 battery saver cord offers a more secure connection, and when powered to a properly charged power box, can push though the correct 12.5 volts probably up to 20 amps + supply. I definitely would recommend this more confident system over the 9 volt wherever possible.
Once again I agree with Jason the 9v battery can work for you no problem, just be aware of the differences etc.
