I had to replace radio now working but no horn or windshield washer checked fuses all ok is there a relay switch that might be fried
Check your fuses in the power distribution center under the hood and the interior fuse panel.
Even the pay sites dont list a schematic for that vehicle. The affected parts are not related by system type. The only common point with them is the BCM and the clock spring. You may need to stop at a dealership and see if they will help you with a diagram etc.
SOURCE: Car Horn
Try using a 12volt jumper wire directly to the horn from the car battery. also check the ground on the horn. The last thing I would do is pull the steering wheel cover. Make sure the horn is blowing first.
SOURCE: 1998 Grand Voyager horn not
You can check the clock spring. Remove the cover over the stealing wheel where the emergency flasher is. At the bottom there are two connector side by side. the small one on the left is for the Air Bag, the one on the right (6-7 pin connector) is for the horn and cruise control if you have one. Disconnect the right connector. Us a wire to gound out the pin in the lelft side of the 6-7 pin connector. If the horn sounds, then it is either the clock spring or the air bad itself that needs to be replaced. I would bet it is the clock spring.
SOURCE: won't squirt, fuse ok...
It needs a motor It is located on the bottom left hand side of the washer bottle. left hand side if you are faceing the front of the car. There is one connector and 2 hose thats you will have to remove. Your going to have to lay on the ground to get it you cant get it from up top.
SOURCE: neither the windshield wiper or washer pump are working
Suspect multifunction switch failure. (turn signals, cruise control, and wipers).
SOURCE: blower motor does not work
I had the same problem, replace, replace, replace. Check, check and recheck. What I found was the blower motor resistor, located in the blower squirrel cage area, two prongs and a curly wire, was bad. Took the new one back, (it ohmed out okay, continuity ok, all ok!) replaced it with another, and Bingo, problem solved. Frustrating to say the least. After two relays and a blower switch, and test, test and retest. It was a faulty resistor. Made in Mexico. And no guarentee, even though new, it works. Trial and error. Even the dealer parts are Honcho en Mexico. Thanks NAFTA. You gonna make us all welfare babies.
