Instrument panel issues... Please help...

[Madcat455]

Hello,

A friend of mine has a 99 Grand Cherokee, V8 4x4. She called me yesterday cause her cars been acting strange.

Started this week, first she noticed the spedo and tach acting weird (jittery, then normal), then after that, it wouldn't start when turning the key.. just turn the key and nothing (no lights, radio, engine turn, nothing). She waited 5 min, tried it again and the guages came on, lights worked, radio, etc.. but the engine wouldn't turn over. On that attempt, her spedo and tach also spun around a full 360deg. She waited another 5min, then the car started normal.... but now her speedo and tach are not working at all.. they'll move slightly when the key is first turned to the on position.. but nothing else.

Finally, her heater core leaked onto the pass floor area.

I have the heater core bypassed for now, while I get the parts to fix it. (it's FL anyway, so heat isn't a big issue.. LOL). But I'm stumped as to what's causing the other issues.

Did Chrysler put the ECM on the Pass floor area??

BTW.. no codes.

Any ideas where I should start??

Thanks.

My wife's Jeep had crazy acting gauges like that and I found out the battery was bad. Changed battery and everything went back to normal. You might just have someone check it.

i would have to agree sounds like a bad battery the ecm is actually under the hood
