Bad vibration?

[kanz24]

God afternoon everyone. I have 2 questions about my 1997 hoe. While getting ohe highway to towing the boat home I noticd a bad vibration coming fom the driveline. Over 55 and the vehicle would vibrate. So like any other good husband I told the bride to stick her head out and tell me where the noise is coming from. Its coming from the passenger side rear. U joint possibly? its really not noticeable at low speeds except for the clicking noise. Oh and it gets better, I turned off the fan for the a/c andnow I have no power to the fan. All the lights for the a/c come on but not the blower motor. Any Ideas? Thanks
Jimmy

ac problem may be the switch itself these are notorious for burning out in our models. Last time mine went it out it did this all the lights came on even the compressor but no fan. If you take the ac switch panel out you usally can see the burn spot or short in the circuit board. Try a local yard first to see if they have one or even LKQ parts it is cheaper than a new one which is about 180 last time I bought mine.

If you floor it, and put it into different gears, does the vibration go away? Or is it only dependent on vehicle speed?

get under and check your u joints. if its 4x4 check the front too.
