I have a 91 300Zx. I have recently lost power to the A/C, windshield wipers, power mirriors, and the rear window defroster. Has anybody had this problem before?

I have an 85 300ZX that has good freon and cannot get cool air into the car. I always have HOT air 150-160 0C, from the defroster outlets. The conrtols have no effect. It seems to be a faulty vacuum problem but I cannot find any vacuum hoses off. The speed control went haywire at about the same time. Anybody had this problem to help me with this?

Its one of the relays behind the fuse box inside the car. The fuse box is located underneath the driver side down to the left of the clutch. To be able to get to the relay you will have to be able to remove the whole fuse box. You will be able to see the relay on the back of the fuse box. How I found the bad reIay I removed one of the relays under the hood that runs the headlights which was already working and enterchanged it with another relay behind the fuse box inside the car until I found the one that went bad. There is more than just one relay behind the fuse box, but just one is bad. We got the relay at Auto Zone. It was around $12.00. Hope that helps!

Try replacing the power supply located under the dash on the drivers side.

My 91 nissan 300zx climate control system unit flashes on and off and I hear a clicking sound from a relay under the steering wheel. All functions- heat and cool and econ- shut cycle on and off with the flashing of the unit. Where should I start?
