Trim Up stoped working

[DarenMB]

92 Cobalt 22T
740/DP290

Trailer button will raise the outdrive and Down button will lower, the Up button quit working.
I tested the switch with a voltmeter, its good. Relay under the dash is good and the trim gauge indicates correctly. Is there a limit switch somewhere?

Check relay(s) on lift motor unit on transom.

Swapping relays produced the same condition

Check that one relay or the other @ the lift motor clicks when Up and down buttons are pushed. Yes, there is a limit switch. Usually at the top of the lift housing. PM me your email address and I'll send you a copy of the Volvo OEM shop manual which has the schematic.

Issue resolved. Bad connection to the Trim Indicator Gauge

Thanks for the resolution report. All too often people fix an issue and disappear silently. Reporting the resolution adds to the knowledge base.
