Make sure the car is OFF.

Open your hood and look on the passenger side firewall between the inner fender and the heater blower motor. You will see a black rectangular device with a grey connector on it. Unplug the connector, and remove the two self-tapping screws that hold this rectangle in.

The device that you just removed is known as a 'resistor block'. Look at it carefully, and you will probably notice that one or more of the coiled wires have separated from the terminals. This indicates a failed block.

You can get a replacement from several sources (Dealer, NAPA, or junkyard).

Installation is the reverse of removal.

That's all there is to it, under 5 minutes from start to finish!

Why would the heat and temperature gauge in a 1995 Plymouth Voyager drop at higher speeds?

It sounds like u need to replace the thermostat. At slower speeds the air flow through the radiator is minimal, but at higher speeds the air cools the radiator more. This only happens if the thermostat is not keeping the water in the engine block long enough.

1996 Plymouth voyager 3.3 liter has a vibration at high speeds and a wobble at low speeds.?

My minivan was doing something very similar. Does the vibration/wobble stop when you let off the accelerator? Try coasting down a hill without touching the gas pedal; if the vibration stops when you let off and then starts again when you push on the gas pedal there's a good chance the vehicle has worn-out motor mounts. I was skeptical when my mechanic told me this, but after he replaced the mounts on my '92 Voyager 3.3 liter there was a huge improvement to the wobble/vibration that I had.

How will it be known when Voyager reaches the end of the solar system and reaches interstellar space?

NASA can predict the speeds of the two Voyager craft very accurately. The main problem is defining where the "end" of the solar system is.

What causes the Plymouth voyager's windshield wipers to quit?

There are two 'relays' under the hood. Check the relay cover (driver's side toward the firewall) to see which fuses and relays are which. As I said there are for the windsheild wipers, another for the hi/low wiper speeds. Check these first by replacing one or both. Should cost app $10 each.

What are wireless router speeds?

Wireless router speeds measure the amount of data that the router can transmit per second. The higher the speed the quicker the data can be transmitted.

Why would your 2000 VW beetle grind downshifting to 2nd gear above 30 mph Other downshifts are fine at comparable speeds?

The most likely cause is that the synchromesh is worn on second gear, if this is the case it's a box out and repair job.
