Is the water cold? If so it is probably due to a condensate drain tube stuck closed. Look for the evaporator enclosure under hood. On the bottom there is a small rubber outlet that will allow condensation to escape. Sometimes they stick closed after a period of non-use. No need to replace it. Just manually open it up and maybe clean out the end a little bit.
I would guess that it is the windshield seals. Check them to see if you can find any gaps on the outside of the weatherstripping.
its a Nissan for starters but it could be the plug wires or the plugs or the distributor
A bad thermostat can cause overheating in a Nissan Frontier when the air conditioning is turned on. A bad compressor can also cause this.
If they are vacuum operated then it could be the hubs.
try replacing the heater core
yes
Theoretically, you can put a Pagani Zonda F Roadster engine in a Mini Coopper S, and they are basically the same type of car (the Navara and the Frontier, not the Zonda and the Cooper), so you could expirement and see what happens.
Not sure...but i guess you could call the car dealership.
In the electrical section of a haynes manual or possibly you could buy e book from internet
If your 2005 Nissan Frontier has a full tank but the fuel indicator shows empty and the service engine light is on, you may need the computer or the "brain" reset or replaced. You can take the truck to a garage or to the Nissan dealer to have this done.
What size engine? The 2.4 is 3500 but will not do it. I towed a 17.5 scout sport fish with it but could not get over 65mph.
try the neutral safety switch
Front shocks. You may feel what I could describe as an "UP" bounce feel. If you replace the front shocks this will minimize that feel. However, the Frontier front suspension is quite "bouncy" good truck.
