'97 Volvo 850 GLT: Fan Relay reliability advice and opinions sought (3545803, 1398845)... getting ready for trip

[jreed]

I'm getting our '97 Volvo 850 GLT wagon ready for a road trip and I've replaced quite a few things already, but never touched these two relays. Curious if anybody's experienced a failure with either of these relays and if so what was the root cause? Are these good candidates to replace or have spares ready to go in case of failure? Thanks for your advice and opinions.

I don’t recall any failure here. If you want some , or other parts for a spares box to return later, pm me though.

I pooched those two thin gauge yellow wires on my T5, be careful with those

The "803" relay is your main FI system relay.

I haven't seen one fail, but the connectors do suffer the same degradation that all of the connectors in the engine bay of these cars seem to.
