94 F150 4WD
6 Cyl OHV
Manual Trans
Regular cab.

It is a sweet truck. Has a lift kit and big tires. Runs great, starts on first turn and drives nice. Has 160,000 miles on it, tranny is only 2 years old.

Okay here are the problems:

1) Heat never really gets nice and warm. Just enough to take the edge off.
2) Windshield wipers don't work.
3) Front differential leaks.
4) In cold weather clutch sticks.

For #1 I think it is the thermostat. I am going to change it out and see if it improves.

For #2, prev. owner already tried new motor and checked fuse. I am going to try a new switch.

For #3, what do I need to fix this? New seal kit?

For #4, we think it is the clutch slave cylinder.

Anyone have advice on the above? For #1 I know I have to drain the coolant. Anybody ever attempt #2? How difficult is it to get the switch out? What about #3 and #4? How difficult. I know for #4 the trans has to be dropped.

Thanks for any and all help.

Oh, one other problem, fuel gauge doesn't work for front tank. Any thoughts on that?

just did my thermostat today. took 5 minutes. didn't drain my coolant. took off top rad hose where it goes onto the thermostat housing and took out the 2 bolts lifted housing and pulled out old thermo and dropped in new one. bolted housing back down and topped off the antifreeze that i lost ( 1/2 gal). do this when the engine is cold. i got impatient and tried when coolant was very warm, maybe that's why it went so fast. as to your front diff, where is it leaking from?

Good question on the leak. It is dry right now, I need to refill it in order to diagnose.

As far as the Thermostat change out, you said you didn't drain any fluid, but did you change the gasket? Would it be easier to drain off about a 1/2 gallon of fluid?

on my 05, the only coolant i lost was what was in the top rad hose and whatever came out when i pulled the thermostat. my thermostat has a rubber o-ring for a gasket, so no scraping off the older style for my truck. for me, not draining all the coolant worked, if you have to spend time scraping a gasket off you will lose more coolant than 1/2 gal.

Some other possibilities with the heater are the temperature blend door or a plugged core or pinched heater hoses.

As for the clutch, suggest to check for any air in the lines. IIRC, some slave cylinders are able to be bled externally without dropping the tranny?? Can you see any leakage indicating a slave cylinder problem.

where is your temp guage running at? in mine it always stayed constant at 1/2 way on the guage. then recently it dropped to between 1/2 and 1/4 on the guage, and when idleing it wouldn't even get to 1/4. also when driving on the highway, whenever i had to slow down, i noticed the guage would cool off. new thermo and now i have to turn the heat down as to the fuel guage, it might be the sending unit in that tank. i think it's connected to the pump.

Well here are the parts to your wipers/

I would say cloged heater core if it is getting heat, but not very hot.

welcome to the site!

1/4, less when it is as cold as it has been and I am moving forward. That is why I am pretty sure it is the thermostat.

On the 96 and older board I saw the exploded view of the steering column (where the switch is), but I still don't know how to disassemble the column to get to it.
