2 questions for a 97 EB

[jwnovaman]

#1 In the last few weeks I am having an issue with the heater. It blows HOT no matter where the temp control is it gets hot inside. Just wondering where to look to figure out where to start.


#2 How the hose routed for the rear window washer? Its leaking and I cannot spray the rear window. The odd part is I can hear the fluid running down somewhere but I cannot see it end up on the ground. On a dry day there will be no puddle under the truck even after trying to spray half the resiviore..

#1: pull the main control panel where your controls are by: 1) "popping" off the trim plate on either side of each vent by sliding something like a credit card, or rubber spatula to ease it out until you can get your fingers behind it and dislodge the snap clips, 2) remove the screws holding this in the chassis; refer to pic attached; its very easy. Then check the plastic electrical connectors. Sounds as if a connector has either come loose, or perhaps broken. they are known to crack after all these years of hot/cold. Reassembly is just the reverse procedure. Sure others will chime in too.

#2: it runs inside under the roof liner along the passenger side of the vehicle to the back.

So the control wire plug is good. Any other ideas of what might be going on?
