A/C and dash lights

Start with checking the fuses. One or more could have blown.

Thanks for the quick response! Fuses are fine none are blown.

At the battery, ensure all wires were reattached. Check for loose connections and at under hood fuse box. Have you checked all the fuses and under dash fuse box?

You would need to check why power supply is missing.

I will do that now thanks!

Please let us know what happens.

Dashboard and radio is back now but a.c. is still off

There are more fuses to check and you will need to see what is loosing power or if it is the ac compressor itself. Here is a wiring diagram and a guide to help you do some simple testing.
