1. Have you removed the touch pad to verify that the multipin connector is connected and secure?
2. The touch pad requires Ignition(or acc) power to power it up. Have you checked that source via the online HWH service manual?
3. Your post is unclear. I believe you stated NONE of the LED lights on the touch pad come on regardless of the slide rooms operating. True?
4. There are 2- 12 volt solenoids at the HWH pump mounted on the motor. The primary, which the main battery positive cable connects to is the "power on" solenoid. THAT solenoid is what is activated by turning the key and touch pad on. The 2nd solenoid just activates the pump motor for hydraulic pressure. Do you have the rectangular control box with the clear plastic cover? Have you removed the plastic cover to check the various fuses AND the tightness of the various machine screws that secure the wire terminals on the circuit board?
5. Have you tried pushing the touch pad buttons REALLY HARD? If you have no LED lights at all when the key is ON, then forget this. Older touch pads get bad contacs and you have to push the buttons extremely hard which means you replace the touch pad.
6. The control box does not really control the slide operation, so your control box may be burnt out. Doug
