2007 387 some issues needs resolving

Hello,

I just recently purchased a 2007 387 as my first truck yesterday, however there are some minor issues that does not affect driveablity except one issue, wiper water pump, that I would like to fix on my own.

1.) The windshield wiper water pump does not work, I am wondering if a universal pump would work? I am not sure if my local truck parts store would have the correct OEM style in stock. I will be checking around this week but would like to know if a universal one will work. This issue needs to be fixed asap so I can pass DOT inspection to get a new tag.

2.) 6 gauges don't work and don't light up, front, rear drive axle oil temp, transmission temp, pyro, air load, and air filtration. It seems common that those don't work as the previous job I had as a driver, the company trucks most gauges didn't work, they were KW T600's.

Is it normally a gauge issue, or wire issue, or sensor issue?

3.) The fridge, it looks like its factory as I have seen it in other 387's that I have checked while looking for the one I got. It doesn't work at all, nothing runs no noise at all. I tried playing with the fridge power switch on the bunk control panel with no luck. This was while engine was running.

4.) Dome light switch does not work as well too. From your experience is it normally the switch itself? All the dome lights work once I open the door. But no way to get it all to turn on when closed.

5.) Driver's mirror, it shakes so BAD while the passenger mirror holds very good. Can it be tightened up if I start taking the shroud off? Also it has exterior temperature which does not work, is it fixable or does that mean I need to buy a whole new mirror unit?

Let me know, I plan to jump into and work on these issues this weekend before I start detailing the truck.

 

I got the truck for a great deal plus some freebies. I knew those items weren't working, its not a big issue about those. I like working on vehicles, and I don't get to work on much anymore like I used to, I'm actually anxious to jump in and fix things, and then clean it up this weekend.

 

Finally got time today to work on the gauges, but first about the windshield water pump, the motor indeed was done. last weekend I went to 2 parts store, NAPA had one the same diameter, and same end for pickup, and electrical connectors, just the connector and pump body was a little longer. But it worked and fit in the snap in bracket just fine. 24 bucks.

Now about the gauges, the rear drive oil temp, i noticed when it was dark, it was lighted up but all 5 gauges weren't. So today I took the panel off, noticed one jumper, just like mentioned by others, was disconnected from the rear drive oil temp. That gauge is the first gauge to get the main data line in. So i plugged it back in, everything worked! However now the front drive oil temp's warning light is flashing. I went ahead and checked the sensor on the front drive, it was disconnected. I didn't get chance to work on it for long, but did try and clean the gunk off the sensor then tried to plug the connector back on. It just wouldn't stay on and didn't feel like it was in contact with the sensor. Tomorrow I will clean it out better and try something out like a new connector made. See if it will work.

No wonder why that guy disconnected it, the flashing warning light is annoying to drive with so he unhooked it. He could have just simply switched the jumper off that gauge and go to the next gauge so then all other gauges would still work. I tried it that way and all 5 work just fine. It's a nice feeling that it was a simple connector issue to fix and to have those gauges especially pyrometer to work!

Now I have a new issue, I never tested this before buying the truck, but the bunk blower for HVAC does not work. I checked fuse box, no fuse marked for the bunk blower motor. I checked the ciruit breaker in the passenger storage compartment, there's no red light. I'm going to have to fiddle around with the connectors under the bed and give the blower its own test 12v to see if it runs to ensure the motor itself is fine.

Is there a fuse or breaker for that blower hidden somewhere that I do not know?

 

I got a new relay for the HVAC in the passenger compartment, that didn't help at all.. I didn't get chance to dig into the wires and blower yet.

I have another question, my friend came up to visit me today, we went for a ride earlier. I noticed that I don't like the accelerator pedal how it works. It has like almost 2 inches of downward play before the ecu sees that I am pressing down on the pedal. I tried doing a calibration known to many electronic pedals, which is key on, press and let go pedal slowly 3 times then key off. Start and see if it made difference. It did not, I even tried again by pushing down and let go 5 times. No difference.

Is there a way I can adjust/calibrate this without needing INSITE?
