Fuse for sun room, 1991 Land Cruiser

If the fuse is OK as you say, it is most likely the switch, a broken electrical line or the drive motor. Try chasing the cable from the switch to the motor and check for 12+ volts at various points with the switch in the "on" position.

Injector pumps rely on information sent from sensors on the engine to ajust fuel mapping, this is also affected by smog reduction systems. In 91 engines were less electronically controlled than they are today. Some of the anti smog systems rely on vaccuum pipes and diaphrams, these systems are often linked to other vehicule systems such as 4x4 operation. you could try unplugging each system to see how it affects performance but my advice would be to diagnose and repair to factory spec. whatever it is that has failed.

english please.

replacment

CHECK SUN ROOF FUSE.IF GOOD CHECK FOR POWER AT SUN ROOF SWITCH.IF YES SUN ROOF MOTORS WIRES COULD BE LOOSE OR BROKEN OR SUNROOF MOTOR FAULTY.

CHECK YOUR FUSE. IF YOUR FUSE IS GOOD, THEN CHECK THE SWITCH, IF YOUR SWITCH IS GOOD THEN REPLACE YOUR MOTOR.

you dont,they are bolted thru the roof to the chassis cage.means taking down roof lining etc (too big a job)
why dont you just mask up around them......paint them with hammerite.

try ebay.....

Does the car have climate control air/con?If so,air/con may still be coming on at different times.I would double check the air/con drip tray.Sometimes it has 2 pipes if the tray has split levels.One may still be blocked.(Does the car have a built in fridge?)Hope this may help

check the sunroof drains,they may be clogged they are located on the right and left front of the sunroof.
