Hello and welcome to JustAnswer!
Warning lights come on because there is a fault code stored in that respective module or that module isn't communicating with the instrument cluster (in which case there are still codes set). It may take some electrical testing at the time the problem is happening to determine what is going on, including a scan tool capable of communication with all modules. It's possible that you have a PCI bus communication issue.
Since you're losing the blower motor also you may have a power distribution issue. You may be losing power to the ABS and airbag modules, which will turn their warning lights on.
If no actual scan tool is available then the first thing I would recommend is a visual inspection of the ignition switch and connector. These ignition switches would sometimes fail causing heat damage to the connector and wiring. If you unplug the ignition switch and find heat damage in it or the connector then the switch and connector will need to be replaced.
