Pull it off and verify. www.avigex.ca/xport/heaterrelay.jpg
...but you had hi speed relay connector problems before...so consider this possibility, as even the lower speeds are fed through the high speed relay in released state...
...or for some reason, though improbable, the high speed relay does not fall back fully to its release position (to allow contact to all lower speeds). ThIs could be easily tested by pulling the relay out and installing a jumper wire from 87A to 30.
