pretty bad
electrical problem
It started as just the blower and stereo cutting out when the blower is on levels 1-4. Then it progressed to the headlights cutting out as well (scary when driving at night). You can turn the lights back on manually.

I just noticed that the driver information panel display was off and the HVAC blower does not work on 1 to 4 settings. The blower works intermittengly on high and I hear a clicking noise under the driver side dash. Headlights also go out when this happens in the auto mode - Come back on though if the headlight switch is turned from auto to on position. Does anyone who has had this problem before have any potential fixes?

Had this problem with the blower/autolamps/and trip computer inop. checked voltage to these devices found only 5-6v (not battery voltage when these devices were off. turn any one of them on and it was 0 volts. Traced voltage loss to high resistance in ignition switch. replace $150. switch and problem was gone. (after 2 days of denial)

The blower motor first started cutting off for a few seconds and then back on. When the blower would cut off so would the rear window defogger and air conditioning light as well as the headlights if the headlights were running on automatic. If the headlights were manually turned on they would not turn off. You can hear what sounds like a relay clicking when it cuts off. Replaced the battery but had no effect, can't find the problem. The problem was intermittent for a while where it would cut off for 10 - 15 seconds and back on. The problem has progressed to where on blower speeds 1 - 4 will not work at all, when you place it on any of those speeds, rear window defogger will cut off as well as the running lights and of course, no air will blow. Speed position 5 on the blower works as well as all electrical while on that speed. The key is the blower speed, it's like something is shorting or not grounded causing perhaps a protection circuit to cut power?
