As per the Haynes manual for your vehicle:
The various relays are mounted in several locations throughout the vehicle, although many key relays are located in the fuse/relay blocks under the intrument panal and the engine compartment.
Hope this helps!

SOURCE: tail lights & dash lights went out.

not likely to have a relay in these circuits. to lose both of these something else like a ground could be the problem. try the tail lights first do you have any thing? brake lights backup light , running light. look for fuse in inside fuse box and check for voltage at the fuse. need more info from you. good luck

If youre changing it because it wont blow, try applying power to it first. It is on the passenger side under the dash if you take off the panel above the passenger feet. has a 2 wire plug in apply 12v to the motor, if it works replace the more common blower motor resistor which is located 3-5inches towards the front of the car from the fan itself. Also be sure to check your fuses.
