Help installing a heated seat in 1999 VW Jetta

Hello, I am adding a heated seat to my 1999 VW Jetta which previously did not have one. I installed the pad in the seat back and the seat bottom. I bought the switch/relay. All that is left is to wire the thing. After a second, closer, look at the wiring diagram I see something called the ''heated seat temperature sensor''. Previously when looking at the diagram I assumed this was part of the heating unit for the seat bottom. It is not. The two pads had only two wires each just like the wiring diagram showed. There was a small pigtail as part of the harness for the bottom unit but no sensor. The callout for the parts shows nothing extra. The parts guy could help no more. There were no technicians around to ask. This sensor goes to ground and the switch per the wiring diagram. I am wondering if anybody has run into this and knows if there is a source for this switch or if I really need it. Thanks, Jim

You need that sensor or you will overheat the heaters and may start a fire. I imagine that the sensor shuts them down when they reach a certain temperature.

Try going to the dealership and asking the guys in the shop there. They would be the ones who could really tell you whats going on.

I hope this keeps you out of the hot seat!

1999 VW Jetta, it overheats even after I replaced the thermostat and the plastic housing on the drivers side of the engine (it was cracked). I let it run with the res. tank open because I thought it might...

Did you install the thermostat backwards? It could be air bound.jack the car up on the side the radiator cap is on and run it to try to purg out air.your new thermostat could be bad. Remove it completely and see what for fan not working check connections and relay.if it has air conditioning that works turn it on and the fans should come on.if not there is either no power or bad fan motor.check with a test light for power at fan motor connection.

Trunk release

I had the same problem with my 96 jetta trek edition, solenoid was engaging but the trunk was jammed, went in via back seat, fold down the seat and crawled into the trunk unscrewed the latch, cleaned and greased the latch mechanism and hinges, then screwed latch back, no problem since. The fusebox is underneath the dashboard, if the fuse is good, test the solenoid to see if it is working correctly, be careful have an expert in electricity do the testing for you, if solenoid is good, might be your switch in your console, if the switch is good, might be mechanical, these are basic troubleshooting procedures.
