Your brake fuse might continue blowing in the 1995 Toyota Camry because you have a wire that is exposed and shorting out. You might also have an issue with the brake sensors.
It's because you have a short current somewhere. You need to check the brake light wiring.
When I had this problem with my 1999 Toyota Solara, the issue ended up being a faulty oil pressure sender unit. The 2001 Toyota Camry uses the same engine (and very likely the same sending unit) as the 1999 Toyota Solara.
It's your wiring, you are putting a Nissan radio into a Toyota so the wiring must be screwed up in there somewhere. The fuse is blowing because a power wire is grounding. recheck the diagrams and correct.
Buy a thermostat and install it.
You have a short current somewhere. You have basically check all wires around the blower, temp gauge and retractor.
there is a short somewhere in dash or heater, you need to fix that to stop fuses blowing
I would suspect it is not timed correctly.
Is the secondary radiator fan coming on when the AC is turned on?
Check your brake fluid level.
dont press the break pedal so much
its either a dead short or not properly grounded check that out
Try behind the change holder. Its definitly behind the change holder. Ours keeps blowing the mileage/spped and pwr windows
