SOURCE: Where is the fuel pump relay located on a 1992 Mercury topaz

the fuel pump relay is located on the left shock tower in the engine compartment in a black box 6x4x1 inches. there are other relays inside the same box which is actually called the ccrm or constant contorl relay module, there should be a double connector with 20 to 26 wires in it, hard to miss.

SOURCE: 2000 Mercury Grand Marquis will only blow hot air when ac is on

needs re-gassing because one line should be hot (feed) and the return cold , This is a specialist job do not attempt to do it yourself because its extremely dangerous with very high pressures involved

SOURCE: Ac blows through defrost only

Your Heater and A/C system is designed to fail in defrost mode. Look for vac issues, and cable issues.

My 2010 mercury milan is blowing hot air instead of cold and sometimes when on defrost it blows out the ac vents and when on heat blows out defrost vents. we have changed all fuses and sensors. Help.


Does the A/C compressor engage whe A/C is turned on ? Low on refrigerant ? These system are very complex an will set diagnostic trouble codes , you're best bet , take it to a qualified repair shop . There are fuse boxes an relay boxes hidden all over your vehicle , i 'd venture to say you didn't check all the fuse's !

Defrorstores stay on ,try to change to floor, ac, heat vent ,deforstores still on 1995 thunderbird lx blower motor works great.


Some cars use vacuum from the engine to open and close the doors that direct the air to different positions. It is possible that the vacuum line to the controls is cracked or disconnected.

I have a 1995 mercury cougar and ijust replaced the heater core(big job) had to remove whole dash. Now the ac works, but i cannot switch from air to heat, or change from defrosters to vent/floor ext... i...


I would suggest that you either left a vacuum line off, or if the blend doors are electric, you might have left one unplugged or a ground wire disconnected.

91 ciera only does defrost, no vents or AC


i believe this is a vacuum operated system. if there is a problem with the vacuum supply to the control unit, it will automatically default to defrost. i would start by checking the vacuum source lines. good luck!
