PB: Radiator fans and AC not working

Alternator is charging well.
Radiator fans are OK.
In fact, I got the problem in a small garage after the cooling has been changed. The guy did not find the problem but he wired the fans with a manual on / off switch inside the car in order I can go back home.

The 2 relays (hi & lo speed) seems to be OK.
The fuses are OK.
There are no OBD errors.
Engine temp gauge is OK.

Other things that don’t work:
• Horn
• Panel lightning if headlights are on
• Outside temp is wrong (zero)
• Battery light is ON

If someone has already experienced such a problem, would be nice to reply.
Thank you

You need to take it to a shop that actually has a clue what they are doing. The circuit needs to be troubleshooted systematically and your guy is an apparent idiot to respond the way he did. Get that stuff removed before you have a fire. You can't safely wire a fan direct.
